Good day to you. In milwaukee, wisconsin, things are calming down at this hour after a night of violent protests sparked by a police shooting. An officer shot and killed an armed man during a foot chase. During the protests, one officer was hit in the head by a brick thrown into his squad car. Police then moved in to clear the streets as you see here, but they say protesters set four buildings on fire. Milwaukees mayor spoke about the shooting. He was hit by two bullets, one in the chest, one in the arm. That individual was a 23yearold man, has died. The officer was wearing a body camera. It is my understanding that the body camera was operating. Because it involved the Milwaukee Police and because an individual was killed, the investigation is being led by the state of wisconsin so the state of wisconsin will be the one that will have access to that film from the body camera and is the one that is now undergoing the investigation. As you all know from what happened from that point, things deteriorated. When i left the scene, which was probably a little after 5 00, there was still calm at that scene. Later in the evening as we all now know, things got out of hand. Mayor tom barrett of the city of milwaukee also saying three people have been arrested. We heard from a witness who says she does not believe the unrest is over in milwaukee. Just basically awe struck and amazement. I never thought i would see my own city in a state of unrest to potential riot, you know . I just never thought i would see it. Were standing here speaking with you, just heard gunshots maybe two to three blocks away. I feel maybe the bulk of the large incidents are over for the evening, but i definitely do not feel that this is over. The officer involved in the shooting has been placed on administrative duties while authorities investigate. Cnn has a crew en route and in place there in milwaukee. Our National Correspondent ryan young, of course, will stay on top of this and bring you any new vemgts as we learn them here on cnn. Moving on now to the state of louisiana under a state of emergency there for the next month due to heavy rains and deadly flooding there. Three people have died and one person is reported missing. Louisianas governor calls the flooding a truly historic event and says that Everyone Needs to be in response mode. We have record levels of flooding along rivers and creeks, and because these are record floods, we dont know how wide the water is going to get in those areas. We dont this is unprecedented so we dont have records that we can go back and see who all is going to be impacted. So far more than 1,000 people and roughly 100 pets have been rescued from these raging flood waters. Cnn National CorrespondentLaura Sanchez has more for us from the flood zone. Reporter the flood waters are starting to recede in some parts of louisiana. Would era getting a clear picture of the extent of the damage, just how bad this flooding was, how strong these waters were. Over to the left of me, were in an industrial yard in amy, louisiana. Thats a body shop. That truck was on the other side of that building. There was a tractor that was helping people get across this flooded area to get to their homes and come back. The truck actually got stuck in the water and had to be pulled out itself. You can also see pieces of asphalt, huge pieces of asphalt that have just been lifted off the ground and tossed about like pieces of paper onto the street. And i want to point something out. You see it across the street here in that area just off the street. That white pickup truck, that was actually a man that was trying to cross the road while it was flooded out. He clearly did not make it across. He had to be rescued by officials. One of the 1,000 rescues that firefighters, paramedics and other emergency officials have had to make here in louisiana because of this devastating flooding. The last thing i want to point out across the street. That trailer, i spoke to the guy that lived in that trailer. He kept it across the street here in the industrial park. Fortunately he didnt spend the night here in the industrial park. He said it ran more than 120 yards and got smashed, flattened against the trees there. I asked how he felt seeing his home flattened and his state in disarray. Heres what he said . Its terrible. The gentleman that has that tractor right there, he lost his house in the flood back in march. He just a couple of weeks ago got his house back in order and hes lost hes lost everything. He had six, eight feet of water in his house. Thats terrible. I mean, theres people thats just, you know, its a sad thing to see. Reporter the major concern now are the cities and towns that are south of here because all of this water that was here has continued moving in that direction. The other question is when is the rain finally going to stop . It had settled down here a couple of hours ago, now its falling again. Experts tell us it will continue at least until monday. National correspondent Boris Sanchez there. Asking the question when is the rain ever going to stop. Derek van dam is here. Derek, from what youve seen, it is a bad situation. Is it going to get worse . Its been consistent since thursday evening local time. There is some light at the end of the tunnel, george. I got to show you an absolutely remarkable video coming from a rescue effort in baton rouge, louisiana. Im going to let you listen to this. This woman survived a near drowning in this flood water thanks to some very courageous men. The womans convertible was about 2 3 submerged. She can be heard asking for help. Were breaking the window. The car keeps sinking and one of the men jumps from the both on to the car, starts to tear through the convertibles fabric roof just moments before he pulls the woman from the sinking vehicle. Watch this. Unbelievable. And, george, it actually is more incredible what he does now. She calls and pleads for him to go underwater to look for her dog who is still trapped in the vehicle and comes up successfully with the puppy. Who is that man . I would love to interview that man. Thank goodness for the volunteers and the authorities out there doing these rescues. Theres been over 1,000 swift water and high water rescue attempts already successful. Unfortunately, there have been fatalities but this is, again, showing you the kind spirited nature of complete strangers helping the communities across southern louisiana. Heres the latest satellite loop. I want to show you the bulk of the precipitation. Theres louisiana, theres mississippi, theres texas. The good news is as i mentioned a moment ago that the bulk of the precipitation is moving away from the affected flood areas, but not before considering or not before producing a considerable amount of rainfall. Over 680 millimeters. Thats roughly 26 inches of rain. Here it is. The future radar Going Forward over the next 24 hours. You can see that more of a sporadic nature of the heavier rain showers indicated with the yell lows and the reds. They become less and less prominent as we go forward in time. Thats because the system is starting to break apart and pull away from the region. I want to show you a flash flooding that was captured by this river gauge. Notice the spike in the river levels there for the comot river in central louisiana. That rose 25 feet in 12 hours breaking previous flood stage records. Im getting my tongue twisted here. Flash flooding occurring across this region. Not good when you see call centers like this, Emergency Call Centers. These individuals, the authorities actually had to evacuate the 911 call center there because of rapidly rising waters. George. What an amazing video, wasnt it . Just to see the woman pulled from the car in the nick of time. Thankfully he was there. Derek, thank you. Aiming for the gold, rio olympics day eight wrapped up on saturday. It was a good day for Michael Phelps winning yet another gold medal. The most decorated olympian ever. He won the mens 4x100 medley relay. This makes for phelps 23rd olympic gold medal. On the track british runner mo farah recovered from a fall to take the gold in the mens 10,000 meter race. Lets go live to rio and what to expect from day nine. Kristina mcfarland is live, lets start with you. Lets start with mo farah. What a performance. Not only did he break out from the back of the pack but he recovered from a fall to defend his 10,000 meter olympic title. Reporter yeah, thats absolutely right, george. It was not so much the fact it was more fantastic farah. Surely only mo farah can fall during a race and go on and win the 10,000 meter. He was clipped and went down. In fact, it was his teammate he managed to collide with. He went on and powered clear of the field in the final 100 meters to win it in a time of 27 05 amidst the kenyans, ethiopians, many runners considered to be the best in the world. Remember, hell be back on wednesday to defend his 5,000 meter title. If he wins that, hell become the first man since the flying finn in 1976 to retain his two olympic discipline titles. It really was incredible to watch last night. Im an old track runner myself. Nothing like these guys. I appreciate the craft. To recover from a fall and to still win, thats just incredible. Lets also talk about Michael Phelps in the pool and the question, will this be his last olympics . Reporter that is a good question, george. Were expecting him to have a press conference later today where he may reveal all. He has hinted, of course, in the past few days that he thinks this will be it for him, but remember he said that at the end of london 2012, didnt he . And then he came back. On saturday night it couldnt have ended any other way. Gold number 23 for phelps. 28 now in total after winning the 4x100 meter medley relay and arguably cementing his legacy as the greatest ever. Perhaps we should have seen this one coming because the u. S. A. Have never failed to win this particular event in olympic history, would you believe. Phelps, of course, the baltimore bullet, handed their anchorman the lead going into the fourth leg. From there, the United States never gave it up. So well have to wait and see. Fingers crossed that phelps may still continue in the Swimming Pool but, as i say, the greatest olympian really of all time. Its likely he may bow out later today. Wow. And looking ahead now. Lets talk about usain bolt and the challenge that he faces with rival Justin Gatlin. From what weve seen so far in the qualifying heat is gatlin even considered a challenge . Reporter oh, absolutely hes considered a challenge, george. Hes run the fastest time this year, and this is the showdown really that everyone is waiting for. Of course, sunday is all about usain bolt. Hes looking to do the triple triple for the first time in history. Remember, thats the 100 meters, the 200 meters and the 4x100 meter relay. Today is going to be the first leg of that. He runs later today around 7 00 p. M. Local time tonight. Yesterday on saturday i had a chance to see him and gatlin run in the heats. Usain bolt running the fourth fastest time in the heat at 10 07 while Justin Gatlin had the fastest time, 10 01. So as i say, this is going to be the showdown, its going to be the head to head. Its good versus evil as people keep calling it here, however, dont forget that bolt does hold the world record and that he has had a season of injuries. This is going to be psychological warfare out there in the 100 meters. Very exciting. Indeed. Christine mcfar land, a little envious of your role there. Watching history as the olympic athletes take to the track and field and the pool. Thanks for your reporting. Well stay in touch with you. Lets talk medal count today. The u. S. A. Won its 1,000th gold medal of all time on saturday. The first country to do that in rio alone there they have 24. That nearly doubles the next closest nation, china, with 13. Brittain pulled away with third in third place with a total of 30 medals and japan still fourth in the overall count with 24. One behind germany pushing them to fifth in the standings.

Authorities briefly opened portions of the border several times in the last few weeks, but this is the first time it reopens as part of the binational agreement.
