[Susan Roesgen, Cnn Anchor:] This CNN SATURDAY. I'm Susan Roesgen sitting in for Carol Lin tonight. Ahead this hour, severe weather slams into parts of the Southern Plains. We've got the up to the minute forecast there and all around the country.
[Unidentified Male:] We learn from every casualty we have and we believe that, over time, using the techniques that we're using, that you're going to see those numbers fall.
[Roesgen:] America's number two military man in Iraq speaks bluntly and exclusively about life and death on the front lines.
[Prince Harry, United Kingdom:] You see so many new kids here, that it's nice, in any way, to know that they're being looked after and at this time, more kids are coming in, which is a problem.
[Roesgen:] Prince Harry carries on his mother's legacy in the fight against AIDS. We'll hear a lot more from him next. But first, a look at tonight's top headlines. A big cleanup for five east Texas towns right now. Take a look at this new video in to CNN. A string of tornado-filled storms wrecked homes and buildings before it pushed on east. We will show you more of the damage and get the very latest weather focus in just a minute. Well, he's still the prime minister, but not for long. Silvio Berlusconi is about to resign from Italy's top job. He'll do that on Tuesday. Italy's top court certified Berlusconi's loss to Romano Prodi after elections earlier this month. Some unwanted attention for the former head of the Food and Drug Administration. The "New York Times" says Lester Crawford is the target of a federal criminal probe. It involves alleged financial misconduct and false statements to Congress. And she's back on television. After four years off the air, Rosie O'Donnell is heading back to daytime TV. She will be the newest co-host of ABC's "The View." O'Donnell will replace Meredith Vieira, who you know is moving to NBC's "Today Show." He is no jumping jack flash tonight. No, sir. Local news reports in Fiji say Keith Richards fell out of a palm tree on vacation. The Rolling Stones guitarist suffered a mild concussion. He's OK. No word on why the 62-year-old Richards was up in the tree in the first place. Well, tornadoes, drenching rain, baseball-sized hail, they've got it all. The weather has really messed with Texas in the last 24 hours. The storm has left some homes and buildings in shambles in five east Texas towns. The winds were so strong that they blew parked planes into each other at an airport. CNN's John Lawrence shows you more.
[John Lawrence, Cnn Correspondent:] If you didn't see it, you may have had a hard time believing it planes tossed around runways in Gainesville, Texas like toys, one on top of the other. The airport's manager was amazed by the sheer strength of the wind.
[Matt Quick, Gainesville Municipal Airport:] And I know some of the aircraft were very large and it takes a lot of force to move those things like it did.
[Lawrence:] Winds estimated at up to 100 miles per hour moved into north Texas Friday night. An emergency management worker in one of the affected areas said they knew the storm was coming, but it simply moved too fast.
[Ray Fletcher, Emergency Manager:] It spun-up real fast on us and intensified very quickly and didn't give us a lot of time to get warnings out.
[Lawrence:] Authorities say the wind, rain and marble to baseball- sized hail destroyed a handful of homes and damaged at least 30 more.
[Fletcher:] Some of the mobile homes were completely destroyed and some of the other homes, with the windows blown out and roofs damaged, were were probably not lived in last night.
[Lawrence:] No serious injuries were reported. I'm John Lawrence, reporting from Atlanta.
[Roesgen:] The fight for Iraq again spills into the streets of Baghdad. The dead now include one Iraqi police officer, killed when a homemade bomb went off next to an Iraqi police patrol. April has been the deadliest month of the year so far for American troops in Iraq. Sixty-nine U.S. service members died there this month. That includes one soldier today, killed when a roadside bomb struck his vehicle. And that figure fueled a sizeable anti-war protest in New York City. Thousands of people rallied in lower Manhattan, among them, activist Cindy Sheehan, the Reverend Jesse Jackson and actress Susan Sarandon. Organizers say they marched for withdrawing troops from Iraq and they marched against any military action in Iran. Al Qaeda leaders have been very talkative this week. Three tapes have surfaced, including one from Osama bin Laden himself. The latest was a video featuring bin Laden's number two man, Ayman el-Zawahiri. For 15 minutes in this tape, he praises the insurgents in Iraq and blasts the president of Pakistan, calling him a traitor. The video popped up last night on several Islamist Internet sites. Now an exclusively CNN interview. He is the American Army officer overseeing day to day operations in Iraq, Lieutenant General Peter Chiarelli. He says the militias, more than the insurgency, are the most urgent threat to Iraq's stability. CNN's Ryan Chilcote met the general out in the field.
[Ryan Chilcote, Cnn Correspondent:] Your military commanders on the ground say their biggest problem right now, a lot of them are saying it's not the insurgents, but these militias militias, armed men that owe their allegiance not to the Iraqi military, but to these various sects. There are thousands of these guys. Some people say more than in the Iraqi military. This is a problem that's been growing. The U.S. military hasn't done anything about it. The Iraqi government hasn't done anything about it. What are you going to do?
[Lt. Gen. Peter Chiarelli, Commander, Multinational Corps In Iraq:] Well, I think you've seen the new prime minister has indicated that that will be one of the very first policy decisions that he makes. I think you're seeing that and I believe that that's exactly what's going to happen. This is a problem that the Iraqi government has got to solve. They're the ones that have to come up with a policy and the Iraqi armed forces will be ready to implement that policy.
[Chilcote:] If they ask the U.S. military to get involved in disarming these groups, is that something you're ready to do?
[Chiarelli:] That's a decision that'll be made, a policy decision that'll be made at levels above me. But I can tell you that I feel fully confident that the Iraqi security forces have the ability to work that problem.
[Chilcote:] U.S. casualties, more than 2,300 fatalities now. About 17,500 wounded. April is now the deadliest it was the deadliest month yet this year for U.S. troops. What's that say to you? Why are the numbers going up?
[Chiarelli:] We had them go up this month. We had them go up this month. We took we had some casualties go up this month. But I've been at this long enough to know that you're going to have months where casualties are going to be higher than other months are. And we look at every one of them. We learn from every casualty we have and we believe that, over time, using the techniques that we're using, that you're going to see those numbers fall.
[Chilcote:] Three years ago, President Bush declared the U.S. military's mission accomplished here. Do you think that there was an under appreciation, an underestimation of the challenges that lay ahead?
[Chiarelli:] I wasn't here three years ago. I'm here today. And I realize that we have challenges. But with soldiers like you saw today, we will, in fact, meet those challenges. They're ready to do the job.
[Roesgen:] The general arrived in Iraq in January and it's his second tour of duty there. Click over to cnn.com for our special report on Iraq. It is constantly updated with photos, videos, interviews and interactive time lines. Cnn.comiraq. Florida prosecutors have charged Rush Limbaugh with fraudulently hiding information to get prescription drugs. But they've also agreed to drop the charge in a year-and-a-half if the conservative talk show host stays in treatment. On his radio show in 2003, Limbaugh admitted that he was addicted to painkillers. Time for our Gas Gauge. Prices are still on the rise. On average, a gallon of regular unleaded costs you $2.93. A year ago, it was $2.23. Democrats accuse Republicans of giving tax cuts to oil companies as Americans struggle with the rising gas prices. In their weekly radio address, Democrats accused Congressional Republicans of continuing to turn a blind eye to oil company activities. And rising numbers at the pump are making Americans pay closer attention to another set of figures the window stickers that tell you human miles per gallon a new car gets. But that's not the only way to lower your fuel costs. Here's CNN's Peter Viles.
[Peter Viles, Cnn Correspondent:] $3 gas makes people do some strange things, like pouring vegetable oil into the gas tank of a classic Mercedes.
[Brian Friedman, Lovecraft Bio-fuels:] Just 100 percent vegetable oil, Wesson, Mazola. You put it straight in the tank.
[Viles:] Lovecraft Bio-Fuels sells old diesel sedans that have been converted to run-on vegetable oil, which sells for about $2.25 a gallon.
[Friedman:] The money stays in the U.S. economy and it's a clean burning car. It's like there's just winners all the way around.
[Viles:] This woman likes the retro look of the cars, but...
[Cleo Baudenbacher, Shopping For A Car:] I'm still visualizing myself putting gallons of vegetable oil right in the tank.
[Viles:] The drawback is you need a diesel engine, which rules out 96 percent of the cars sold in America. Ethanol blends like E85 that's 85 percent ethanol can be cheaper than gas in some places, but E85 is not widely available. You see electric vehicles on the road, but no major car maker is marketing them to consumers, who complain about having to charge them so often. And politicians talk a lot about hydrogen and fuel cells...
[George W. Bush, President Of The United States:] What you're witnessing here is the beginning of a major change in the driving habits of the American people.
[Viles:] ... but the fact is you cannot buy a fuel cell vehicle today and no one knows for sure when, or even if, Detroit will produce them. And that leaves the old-fashioned option shop for a mass produced car that gets better gas mileage. A good rule of thumb fewer cylinders means more miles per gallon.
[Joe Caracciolo, Colonial Honda:] So the four cylinder cars are very, very popular right now.
[Viles:] Hybrids, which run-on gas and electricity, offer the best mileage. This Honda Civic hybrid gets an estimated 51 miles per gallon on the highway and 49 in the city. It's roughly $4,000 more than the conventional Civic and there's often a waiting list, but you do get a federal tax credit of up to $2,000 if you buy one. [on camera]: And one more thing to consider if you're shopping for a new car and you're very concerned about gas mileage and that is that you cannot rely on the accuracy of those EPA gas mileage estimates that are on that sticker in the window of a new car. In almost every case, your actual mileage when you drive the car is not going to be as good as those EPA numbers. Peter Viles for CNN, Glendale, California.
[Roesgen:] Somehow we figured that. But how about $0.40 a gallon? That's the price you pay for gas when your country has the second richest oil reserves. But it does come with its own set of problems. That story is ahead. Also, AIDS, Africa and a prince on a mission. Up next, Princess Diana's youngest son reaches out to children facing an epidemic. And, it's a creative competition for high school students the robot rivalry, in about 35 minutes. You're watching CNN LIVE SATURDAY. Stay with us.
