[Anderson:] you're watching CNN. And this is Connect the World with me Becky Anderson. Welcome back. Now in startling, terrifying scene today around Dallas, Texas. Have a look at this video. It shows one of at least two tornadoes that touched down in the DallasFt. Worth metropolitan area within the past few hours. Now the twisted barreled over a tractor trailer depot, hurling huge trucks. And here D well, like they were playthings. There was also extensive property damage in residential neighborhoods. So far no reports of injuries or deaths. Warnings have now been canceled in the area, but a watch remains in effect for the next two hours. And more on that of course as we get it. 15 million people at risk of starvation, a million of them are kids. All of them live in the Sahel region of Africa, a belt of arid land that stretches across the continent below the D excuse me Sahara Desert. The region is in the midst of a severe prolonged drought. Eight nations from Senegal to Chad are experiencing the worst conditions. UNICEF officials say these people can be helped. Time is of the essence. David McKenzie with more from Chad.
[David Mckenzie, Cnn International Correpsondent:] This crisis is affecting the Sahel region of Africa, between the Sahara in the north and the equatorial forests in the south. UNICEF says that more than a million children could face starvation in these eight countries, because of climate change and food prices, and also regional conflict it's difficult to get the aid out to people. These programs are woefully under funded. They say this is the edge of a crisis, that people need to act now, go on Twitter and Facebook and join the conversation and try to help the Sahel and its people. David McKenzie, CNN, Djimena, Chad.
[Anderson:] Well, aid workers say the situation is rapidly deteriorating. My colleague Jenny Harrison with more on that. Jen, what have you got?
[Jenny Harrison, Cnn Correpsondent:] Well, it's a long [inaudible]. A drought like this with this significance does not occur literally overnight. Let me just show you again the region that David was referring to there. Look how vast it is, stretching literally from the west out towards the east to the horn of Africa. And what you have here is two very different climates. Of course, to the north we have the Sahara Desert. And then we have the wetter lands further to the south, but in all this is an area covering 3 million square kilometers. It is hugely dependent on the Intertropical Convergence Zone. We call that the ITCZ. And these rains shift depending on the season, so in January they are to the south. And as we go through the spring months it pushes up towards the north. And during the summer months it's this pretty much across this region the Sahel. And this is the rains that are so desperately needed and relied upon of course from one year to the next. Now what has been happening is that we haven't seen these rains. The drought is in extreme situation across much of the east D Ethiopia, also Uganda. And then out towards the west as well. Here we are in a severe state of drought. So if we take this area to the west, I want to show you this graph that goes back to 1900. Now look at the first D my goodness D years up to 1970. You see this line and you see all these black bars above it, that is good, some very good rains during those years. Since 1970, just have a look at this, there have been only four seasons with average or above average rainfall since 1970. And as we've been saying, of course, the number of people that are so impacted D 10 million, a million of them children. we're so reliant, Becky, on these rains in terms of what's going to happen through the spring months looks as if the east is going to see some pretty good rains. That gets worse through the summer, but out towards the west, we should see some above average precipitation D Becky.
[Anderson:] That is good news. Jenny, as ever, reminding us exactly why we should care about that story. Thank you, Jen. Look at some other stories that are connecting for you tonight. And James Murdoch has stepped down today as chairman of British satellite broadcaster BSkyB. Felicia Taylor is on that story. The second resignation this year, Felicia, for the son of media mogul Rupert Murdoch. Why this? And why now?
[Felicia Taylor, Cnn International Correspondent:] Well, what this does is basically the conclusion has been made that it could have been too damaging for him to stay on as chairman and CEO of the company, because there are still critical verdicts that could come down from a writ of parliamentary inquiries. So this removes him from that position. The reigns go to Nicholas Ferguson who was the deputy chairman. And it's from a shareholder's perspective this is actually good news, because it removes any kind of uncertainty that there was of him being at the helm. Now as I mentioned, there is still a critical verdict that could come from another inquiry from the British parliament, but there's also regulators that are looking into whether or not BSkyB is fit and proper to broadcast. If they are deemed not to be and their broadcast license is taken away that can escalate things here in the United States with escalation in terms of allegations of foreign corrupt practices act. We spoke to one defense lawyer who told us that those penalties could be very severe D listen.
[Brad Simon, Defense Lawyer:] News Corp. could be on the hook tens or even hundreds of millions of dollars if they ultimately settle, or if convicted as far as crimes. Not to mention the potential risk of individuals, high ranking individuals of News Corp. getting indicted and possibly going to prison.
[Taylor:] How high? Like Jamie Murdoch? SIMON; Absolutely. Now this report could come shortly after Easter. So this story is far from over. And there certainly will be headlines to come D Becky.
[Anderson:] Felicia, thank you. we'll take a very short break here on CNN. When we come back, at age 36, a ripe old age, Tiger Woods ready to play the Masters, for get this, an 18th time. His chances, we're going to chat about that after this.
