Injured now, more than 80 people arrested. Also, new details of the first facetoface meeting between trump and putin. It ran more than 90 minutes over schedule and began with mr. Trump raising concern over russian cyber meddling in his u. S. President ial campaign. Russias foreign minister said mr. Putin denied interference and mr. Trump accepted his word. That account is denied. We have exclusive cnn reporting tonight on the fight against isis. Our Nick Payton Walsh and his crew gained rare dangerous access inside the selfproclaimed capital of raqqa, syria. U. S. Backed forces are tightening their circle around the city tonight with terrorists, fighters struggling to hold onto their dwindling ground. Were covering all that and more this hour with our guests including British Defense secretary Michael Fallon and the top democrat on the Senate Foreign relations committee, the senator ben card on. Correspondents and specialists standing by. We begin with the wave of violence around the g20 summit. Cnns Senior International correspondent fred is in hamburg, germany. Frederick, were seeing new protests tonight. Still violent there, still dangerous on the streets of hamburg. Reporter yeah, jim, youre absolutely right. We have to move now, apparently the police are charging the protesters at the moment. Wait, wait, stop. Jim, we had to run a little bit there. Keep yourself safe. Reporter tear gas. Looks like the police fired some tear gas. We are now starting to feel as well. Were going to make a little move back, but this is whats been going on, jim. There have been skirmishes between protesters and Police Officers on the ground. There have been barricades that have been burning. Weve seen the police make a move forward, charge the crowd here. And thats what really caused us to make this move. Youre hearing bangz, flash bangs the police are moving as well. Protesters for their part have been attacking the police with bottles. Theyve been throwing rocks also. Its been a charged atmosphere. As you can see it is not showing signs of letting up. I have to say ive been reporting on this country for a very long time and its been a long halftime since ive seen Something Like this in a german city. Fred, it looks like its gotten much more dangerous just in the last hour there. The booms were hearing are flash booms, this is not gun fire . Reporter no, its not. The flash bangs being used are being used by the Police Obviously to drive people back. There are no gunshots here. Youre right, it has gotten a lot more dangerous, a lot more violent i would say in the past hour or so since the last time we spoke. Weve seen the police are making a move forward. Before that you had the protesters sort of setting barricades on fire, police keeping them back using the water canon trucks. Thats now changed. The police themselves are now moving forward, certainly trying to cord on the protesters if not trying to make it stop. Not showing any signs of doing that. There are many streets here in hamburg where this is still going on here, very close actually to where the g20 summit is taking place, jim. What are the protesters trying to accomplish here, and whats led to these more violent clashes just in the last hour . Reporter well, you know, obviously many of them are voicing their displeasure at the g20 being held here in the city. Many of them have a political agenda as well. They feel that, a lot of the folks are commenting their policies are not fair to ordinary people. Not just here in germany, but of course around europe as well. And what they want to do is they want to disrupt the g20 summit and weve already talked about it. Some of that, theyve been successful with some of that. For instance, disrupting the first lady, that she wasnt able to go to one of the appointments she was to go to organized by Angela Merkels husband. There have been other delegations that have had a harder time moving around hamburg. Its the general disruption i think these folks here want to achieve. Of course, they also want to make sure that the World Leaders that are assembled to hamburg, that they see whats going on here on the streets, that they certainly while they are in that bubble, that they still see whats going on and what they are doing here. First thing i want to say is if you have to move at any moment, fred, move. Your safety far more important than anything. Reporter sure. Is there a sense as youve been watching this over the last several hours that police are losing control of the protests . Reporter no yeah, i think that in certain areas its very difficult for them to come to grips with it. In the immediate area around the summit venue, they are certainly not losing control. Here in the streets, you know, you dont see many Police Officers right here inside the cordoning they have sort of formed around this neighborhood here. Certainly there is no Police Presence whatsoever. You could say theyve lost control here to a certain extent in some of the streets. Weve seen i also have to say, some looting going on of shops here in the area. Weve seen scaffolding that was damaged as well. Yeah, there certainly isnt a Police Presence where i am right now. I wouldnt say on the whole, though, theyre losing control of the situation in hamburg. I think they still are very much in control. However, it is proving very, very difficult for them. They had 20,000 Police Officers in and around here when all of this began. Theyve already decided to call for reinforcements. They have 46 water canon trucks they have been using extensively. The scenes were seeing tonight, we had the bon fire the last time we spoke. Were already seeing barricades. We have to move again. Sorry about that. Stay safe. Well be checking in with you throughout the hour. Again, youve been watching live pictures there of increasingly violent protests this in hamburg germany. Very close to where World Leaders, including President Trump, are meeting right now. Now lets delve into the much anticipated meeting between trump and putin at the g20 summit. Cnns senior Diplomatic CorrespondentMichelle Kosinski has been working that story for us. Michelle, we are learning new details tonight about what exactly was discussed and how it was discussed between putin and trump. Reporter this is a very private meeting. So, the insight we have as to what happened comes from secretary of state Rex Tillerson who said that president s trump and putin had a quick connection and a positive chemistry. Trump seems to relish the element of surprise or doing the opposite of what the analysts or even some within his own administration think he will do. Tillerson today said that instead of avoiding the subject, trump opened the meeting by raising concerns over russias meddling in the u. S. Election. Appreciate it. President putin and i have been discussing various things and i think its going very well. Reporter the handshakes were public. The meeting, private. The briefing afterward, no cameras allowed. Secretary of state Rex Tillerson detailing how he says the first trumpputin facetoface meeting played out. The president opened the meeting with president putin by raising the concerns of the American People regarding russian interference in the 2016 election. They had a very robust and lengthy exchange on the subject. President putin denied such involvement. Reporter tillerson says trump pressed putin more than once on cyber meddling, but then moved on to avoid it being nearly an argument. Russian foreign minister had a different version of events. Translator President Trump said he heard putins very clear statements that this is not true, and that the russian government did not interfere in the elections, and that he accepts these statements. Reporter the white house responded saying there was no acceptance of the russian view. Really only trumpputin, their top diplomats and translators know exactly what happened. Was it brought up where he said some people in my country are exaggerating or pushing this narrative and, you know, we need to bring this to an end. Or was it i know for sure, despite what ive said to the press, that you were involved and this has to stop. Did he say there will be consequence . So, all of that detail is missing. We may never find out. Reporter on thursday in poland, President Trump would not say for certain if russia was responsible. A lot of people interfered. Reporter when tillerson was asked by reporters, though, whether trump was unequivocal that russia did meddle, he didnt answer. He called the meeting constructive, a good start. The two leaders, i would say, connected very quickly. There was a very clear positive chemistry between the two. I think, again and i think the positive thing i observed and ive had many, many meetings with president putin before is there was not a lot of relitigating of the past. Im delighted to meet you, mr. President. Reporter though the initial greetings for the cameras were somewhat stiff, tillerson told reporters there was so much to talk about, it was difficult to stop the two hour 15 minute meeting. After the first hour the first lady came into the room asking if they wanted to wrap up, but the discussion went on. Syria being the focus, they were able to announce today an agreement between russia and the United States on a cease fire in southwest syria starting sunday. And on the cyber issue, an agreement to discuss a framework and commitments to not interfere. Though clearly there remains a big gap in approach here. The real question is how do you deter him from acting in that way in the future. What are the punishments and the costs that President Trump would impose on russia to ensure they do not repeat that action in 2018 and 2020. And he did not do that. Reporter there were plenty of questions here. I mean, did the subject take up 30 seconds before they moved on, or 30 minutes. Remember, the u. S. Intelligence community believes it was not not just russia, but putin himself who ordered this intrusion into u. S. Democracy. This administration has not answered the question of what do you intend to do to punish russia, or to make sure that this does not happen again. The extent of what we heard today from secretary tillerson was that trump did bring up the fact that the senate at least has passed a bill to strengthen sanctions against russia, and he did that to show the seriousness of the issue. Jim . Cnns Michelle Kosinski at the state department, thanks very much. We continue watching the situation on the streets of hamburg where police are using tear gas, water canons to push back protesters who have been setting fires, looting buildings, injuring dozens of Police Officers. We are also following the disagreement tonight over key detail of todays meeting between President Trump and president putin, whether trump accepted putins denial that russia meddled in the 2016 election. Cnn senior White House Correspondent jim accosta has been covering that part of the story for us. Jim, you spoke to Administration Officials tonight who pushed back really against russias account that President Trump somehow accepted putins position. What more have you been learning . Reporter thats right, jim. A Senior Administration official told me the president did not accept Vladimir Putins claim of noninterference in the last election. That was after the Russian Foreign minister Sergey Lavrov told reporters he had in fact accepted putins denials. That is going to be a nagging question for this white house moving forward. There are questions by Clinton Campaign officials. The president needs to stay on camera. Secretary tillerson painted a different picture to reporters saying both sides could not come to an agreement at all on this issue of interference and said that the question moving forward is what do we do now. That is a huge question, jim. What do we do now . Both sides do not have any answers so that question today. As you know, cnn had been told by Administration Officials that the president was not initially planning or they didnt expect the president to bring up election meddling. Have Administration Officials explained a change of heart in this meeting . Reporter not yet, and it is a seemingly very big change of heart, jim. Just yesterday, as you know, the president insisting it wasnt clear that russia alone was meddling in last years election, adding other countries could have been involved. Contrast that with today and tillersons account the president brought this up right away. That is a sign that perhaps the president is listening to his critics. But keep in mind the president also, according to Rex Tillerson, was passing on what he described as the concerns of the American People. So, its not clear that the president was passing on his concerns and one has to assume based on what he said yesterday that he was not passing on his concerns, but the concerns of people back in washington. And also look to what happened earlier today. The president was still blaming others for the election meddling. He slammed Clinton Campaign chair john podesta for not turning over dnc servers to federal investigators. That, of course, is not something that podesta can do as he was running the Clinton Campaign, not the dnc. So, as of this morning the president was still deflecting on this issue. I think thats a pretty clear indication, jim, that the president has not had a change of heart on this issue but felt compelled politically to bring this up with putin in this meeting. If he had talked to putin two hours and not brought this up he would have big political problems heading back to washington, jim. Jim accosta, thanks very much. Lets get more from senator ben card in, the senior democrat on the Foreign Relations committee. Thanks for joining us this holiday week. Jim, its good to be with you. Thank you. As you know, just reminding our viewers, you and a handful of other Senate Democrats wrote a letter to President Trump ahead of this meeting actually urging him to raise russian hacking during the u. S. Election. We are told by secretary tillerson that he did. Are you satisfied that he led this meeting with it . Did he do what you had pushed him to do . Well, it was very important that this issue be raised. So, i am certainly pleased that it was the subject that was brought up during their meeting. Obviously we dont know the details of the conversation, but it was important for the president to make it clear that we know russia interfered in our elections, that if they continue this pattern, there is going to be additional sanctions that will be imposed and were not going to stand by and let russia interfere with our democratic system. That was the message i hope the president delivered in a very clear manner with mr. Putin. As you know just yesterday President Trump in his press conference undermined his intelligence agencys assessment it was russia who directed these election hacks, raising doubts, raising the possibility of others being involved even though u. S. Intelligence says it has seen no evidence of that. For viewers back home, for americans, how should they rectify the president s Public Comments yesterday, questioning whether russia was behind this and tillersons account today that the president raised the election meddling forcefully in his meeting with president putin . Its hard to understand why President Trump undermined the Intelligence Community with this statement yesterday or day before. Its very difficult to understand. Russia clearly interfered in our elections. Intelligence communities made that very clear. And yet the president raised doubt about that just a day ago. That makes no sense at all and didnt give him the strongest hand going into meeting with president putin. We hope that he clarified that and made it clear to president putin there was no doubt from our information that russia interfered, and we will not tolerate that. Sanctions have already been imposed, additional sanctions will be imposed if they continue this behavior. Thats the Important Message that he had to give to mr. Putin. I cannot explain why mr. Trump does certain things and undermines his own statements at times. Its difficult to understand. Youve been a strong proponent of stepping up, in fact, pressure on russia as a result of election meddling, the Senate Passed a new sanctions last month a rote of 982, obviously bipartisan. The house has its own bill but thats been delayed because the white house opposes some details in that legislation. Now there is talk that that issue has been resolved. From where you sit, are the senate and house going to be able to agree on a piece of legislation imposing new sanctions on russia for election interference . Well, i certainly hope so. Our bill passed 982. It was very bipartisan, a very strong bill. It speaks to the appropriate role for congress. We think it gives the president a much stronger hand in dealing with mr. Putin
