Test. If r the announcement coming on north Korean Television this morning. It appears to be far larger than the norths previous two nuclear tests. The u. N. Security council has now called an emergency meeting. And the white house has issued a strongly worded statement. Lets get, right now, to Abcs Martha Raddatz in washington with the latest. Good morning to you, martha. Reporter good morning, josh. This test was big. As much as three times the size of previous tests. It was bold. Even china, north koreas staunchest ally, had north korea not to test a nuclear weapon. And it is the clearest sign yet of the new leaders belligerence. This is the First Nuclear test under kim jongun, who said the test is aimed at ferocious u. S. Hostility towards north korea. In december, un also successfully tested a longrange missile, capable of reaching hawaii. The white house is calling this a highly provocative act. And calling on actions from the International Community. Theres very little the u. S. Or the u. N. Can do at this point since strong sanctions are already in place. In fact, this morning, north korea is saying, we will consider search of our ships and other sanctions by the International Community as an act of war. And, josh, they say it will bring on relentless retaliatory attacks. We will certainly keep our eye on this. Martha, thank you for that. Meanwhile, theres word this morning of a new poll out, planned for the u. S. Forces in afghanistan. The pentagon is reportedly pushing a timetable that would keep some 8,000 troops in the country after the mission officially ends next year. White house advisers have pushed for a more aggressive withdrawal. The president is expected to announce a final decision soon. An outpouring of support in texas, for the man known as the deadliest sniper in military history. Nearly 7,000 people turned out in cowboys stadium to honor and remember chris kyle. He was killed at a shooting range near dallas, by a fellow iraq war veteran who told authorities he was suffering from posttraumatic stress disorder. And this morning, police near minneapolis are trying to figure out why a man was randomly firing shots at cars driving through an intersection. One of the bullets struck and killed a 10yearold boy who was riding in his mothers minivan. Police arrested the shooter a short time later. A new move by twitter to become a shopping destination. Now reached a deal with american express, that will allow cardholders to buy products from the site for the first time using a special hash tag. Twitter has been exploring new ways to make money so it doesnt have to rely solely on advertising. In arizona, a video released showing a nearcatastrophe in the desert. The reality show here filming a stunt where a corvette was racing a helicopter. Seconds after the race had finished, look what happens. The chopper pilot loses control. And that helicopter dives nosefirst into the ground, just feet from the crew filming it all. Remarkably, the pilot suffered only minor injuries and walked away from it. The crash blamed on a mechanical failure. They were filming for a south korean show. We will not show it on television. We just did. Right . Thanks to you. News breaker that you are. All right, josh. Were going to turn to rome and the latest on the popes startling resignation. The first time in 600 years a pope has done this. But take a look at this photo. Its going viral, madly monday. Of a bolt of lightning striking st. Peters, the same day the pope announced he will step down. Benedict is set for a new name, a new home and a new role. After his unprecedented move. Dan harris is live in st. Peters square this morning with all of that. Dan, good morning to you. Reporter elizabeth, good morning to you. Heres how the local papers are playing this huge story. This one says, in italian, pope shock. And heres a headline we can all understand in any language, amen. As catholics all over the world absorb this truly stunning news, today, were starting to get a sense of what may have provoked the pope to make this announcement now. This morning, an Italian News Agency says the pope had a topsecret operation to replace his pacemark ker at this hospit in rome three months ago. The vatican wont confirm the news. But the paper says the operation went, quote, well. The popes older brother held a News Conference the day the decision was well thought out and nobody pushed his brother out. Meanwhile, benedicts surprise decision has provoked vatican intrigue, worthy of a dan brown novel. Jockeying and politicking has begun over who will be the 266th pope of this 2,000yearold church, the largest religious body on earth. If i was a cardinal and i really wanted to be pope, could i actually campaign for myself . Well, i guess it would appear indiscreet. Reporter it would not go over well . No, i dont think it would go over well. Reporter while there are no clear favorites, bookmakers are laying odds. And here are three names youll be hearing a lot. Cardinal Peter Turkson of ghana is listed as a 94 favorite. He would be the first black pope. Reporter canadian Cardinal Marc ouellet, a 52 favorite. And archbishop angelo scola of milan, who has a strong power base. Roughly 120 cardinals will gather under heavy security and beneath a cloak of secrecy for the conclave to choose a new pope inside the sistine chapel. Every time they vote, they burn the ballots. Black smoke means no pope yet. White smoke, a winner. Its not like voting for a president , where youre voting for the guy who will lower your taxes. Precisely. I want to vote as for the man god wants. Thats a very scary thing. Reporter scary, indeed. One more picture i want to show you this morning. This is the building where Pope Benedict will live once he officially steps down on february 28th, at exactly 8 00 p. M. This is a former monastery inside vatican city. For months, construction crews have been rehabbing this building. During that entire time, only a few top vatican officials actually knew this would ultimately become the popes retirement home. George, back to you. Almost everyone in the dark. Okay, lets get more on this now from vatican media adviser greg burke, who is in rome this morning. Thanks for joining us, greg. Lets begin with more on the popes health. We learned about the operation on his pacemaker a few months back. The resignation has been in the works for some time. What else can you tell us about the popes health right now . The popes health right now is what you see. And well see him again tomorrow. An 85yearold who is almost 86, who is starting to slow. Essentially, he does have that heart condition. And that wasnt the reason, obviously, for the resignation, however. People have pacemaker batteries replaced all the time. That does happen. But essentially, its of age. His mind is obviously clear. We saw him talk a couple nights ago off the cuff. He was very, very clear. But its more in mobility and slowing down a bit. But nothing immediate. Theres been rumors of bone cancer, as well. Thats certainly not true. Nothing immediate. Just age catching up with him. The pope will be living in the vatican. Hell no longer be pope. Hes going to go back to being a cardinal. Take his old name, joseph ratzinger. Will he be able to counsel the next pope . Well, if the next pope would like it, im sure he could. However, if some people have suggested, wait a minute. Youre going to have two popes at work. Thats not true. The pope is retiring because he wants to retire. If he wanted to have influence on the church still, he would stay as pope. I would expect very much the fact hes going to a monastery will be living in a monastery is significant. He wants a quiet life of study and of prayer. I assume that if the new pope wants to ask his counsel, hes clearly going to give it. But hes not going to go hes not going to be there looking to try to influence the next pope. And the new the cardinals will be meeting right after the pope resigns on february 28th at 8 00 p. M. Will the deliberations about the next pope begin immediately . They could begin. Well find out that in the next few days. They could technically begin as early as the day after, as early as march 1st. But you have to remember, its never the conclave, which begins initially. First, they have general congregations, where all of the cardinals gather to talk about the main issues in the church, even those over the age of 80. Even those that wont be going into the eventual conclave. First, theres several days of general meetings, of all the cardinals. They could start as early as march 1st. But that hasnt been decided yet. Oddsmakers already hard at work. Do we know if Pope Benedict has a favorite . It would be hard to tell that Pope Benedict has a favorite. You can look at the men he chose. And obviously, i think each one of those, the college of cardinals is made up of cardinals by Pope Benedict and Pope John Paul ii. You can see who Pope Benedict chose for whatever reasons. I dont think he has a favorite. And hes certainly not going to show that he has a favorite in these days. Okay. Greg burke, thanks very much for your insight. Elizabeth . Unchartered territory. Turning, now, to the latest on that frantic manhunt for the rogue exPolice Officer, christopher dorner, on the run right now. We showed you the Surveillance Video that surfaced overnight. Could it be a clue to where he is at this moment . Abcs Pierre Thomas is tracking the latest on this story. In los angeles. Pierre, good morning. Reporter good morning, elizabeth. Its becoming clear dorner could be anywhere. And this morning, theres evidence the hunt for him has gone international. Overnight, Police Conducted a raid at this hotel in tijuana, mexico. They apparently found no evidence he was there. But for days, Customs Officials have been hunting for dorner along the southern border. And theres new details this morning about dorners possible movements in the days before the shootings. Tmz obtained this Surveillance Video of a man who looks like dorner buying scuba gear, reportedly days before the killing began. And there are new reports that dorner checked in this navy gateway and suites hotel in point loma, california, the same day, using his navy i. D. Trying to purposely avoid the cameras. Reporter the news surfaces as dorner faces capital charges, that involve the murder of riverside officer, michael crane, gunned down last thursday. He was married with two children, ages 10 and 4. This individual, by both his words and conduct, has made it very clear to all of us, that every Law Enforcement officer in Southern California is in danger. Reporter with the possibility of dorners trail growing cold, the Los Angeles Police chief issued a warning to the public. Dont think its just about protecting cops. This man is a threat to every person in los angeles. Reporter a city in fear is fighting back. The 1 million reward, now being offered, has led to a surge in tips. In total, more than 700 calls about clues have come in so far. Sources tell abc news, police are trying to reconstruct the last six months of dorners life. Theyre looking at all his associates, including someone identified as j. Y. , in Court Records obtained by abc news. Investigators believe he has ties to property where dorners burning truck was discovered. Pierre, thanks. Now, to washington, where tonight, president obama will deliver the first state of the Union Address of his second term. The white house promises a focus on the economy. The audience will be packed with victims of gun violence and advocates of gun rights. Jon karl will be there, too. And jon, this has set up an interesting dynamic. Most of the words will be about jobs. But most of the emotion will be around guns. Reporter thats a good way to look at this, george. There will be victims of gun violence throughout the visitors gallery, including in the first ladys box. Youll have somebody tied to the newtown massacre. And also members of congress, who each get only one ticket to the gallery for a guest, usually family member. They will be giving many of their tickets to victims of gun violence. But the message is all about the economy. The white house says that is the message here. The president wants to drive home who has been a theme of his, which is the middle class is the driver of economic growth. And in a challenge to republicans saying, we cannot cut our way to prosperity, look for new initiatives, new spending in this speech, to stimulate economic growth. And the answer will come from the republicans, senator marco rubio chosen to give the official response. It will be in english and spanish, of course. Hes a rising star, the senator from florida. Reporter thats right. His speech will be entirely in english. But he is pretaping an entire response in spanish that will go out on the Spanish Language networks. Rubios message will also be about the economy. Hes leading the charge for republicans on immigration. That will be mentioned in the speech. But again, his challenge will be to the president saying, we need a smaller government, maybe a more efficient government. But a smaller government. And there will be a separate Tea Party Response from senator rand paul. Diane sawyer and i will anchor the coverage of the state of the union at 9 00 p. M. Eastern, 6 00 pacific. Should be an interesting night, george. Were going to turn to the vacation nightmare. The Carnival Cruise ship that has been stranded in the gulf of mexico. Instead of trying to go to mexico, the ship trying to get to a port now in mobile, alabama. Matt gutman has the latest on the story. Reporter for the thousands of people aboard, another day aboard a cruise ship where life is not a vacation. The decision overnight to tow the crippled triumph, seen in these new photos, to alabama, could be making a brutal voyage even worse. And for the first time, we are hearing from passengers aboard that stricken ship. Theres no lights, no water. We cant flush. Some people were able to shower. Reporter conditions are getting worse by the hour, debra rightmire texted abc news. Cabin carpets are wet with urine and water. Toilets are overflowing inside our cabins. Were having to sleep inside the hallways. Onion and cucumber sandwiches last night. The triumph, which is bigger than the titanic, is running on emergency power. Its being towed at a torch rousely slow pace of a few miles per hour. Shelly crosby texted us, we have a lot of tent cities ondeck. And while carnivals ads boast limitless food, thats not the case on the triumph. We just stood in line for four hours to get a hamburger, crosby texted. Cell phone reception is just as scarce, coming only when another carnival ship pulls up to drop off supplies. If you can imagine, 4,000 people running to these single bathrooms. I mean, its horrible. Reporter brent nutt managed to briefly speak to his wife, bethany, and her friends on the crippled ship. All you hear on the phone calls is crying. And talking about, im going to die. Im going to die. Reporter carnival acknowledges there are issues. Tells abc news, theres plenty of food and water aboard. And its working on the sanitation problems. The ship is listing 4. 5 degrees. Thats because the wind is pushing it at 25 miles per hour. Certainly not making the trip home any more comfortable for those aboard. All right, matt. Tough times for those people on the ship.
