At least two U.S. soldiers were killed in separate attacks on convoys, the military said Wednesday, including one on the outskirts of the northern city of Mosul. Spc. Brian Sharkey said the attack near Mosul happened as a military convoy was traveling near the town. He said one of the vehicles was destroyed by a roadside bomb. An Associated Press reporter in Mosul, 260 miles north of Baghdad, heard a large boom shortly before noon (5 a.m. EDT). Six soldiers were wounded in the attack, but the name of their unit wasn't immediately available. Another convoy was attacked in Ramadi, 60 miles west of the capital, Baghdad, killing one soldier and wounding two more. ** Saddam Sons Slain in Mosul?*** U.S. troops, acting on a tip, stormed a private villa in the northern Iraqi city of Mosul yesterday, killing Saddam Hussein's sons in a fierce six-hour firefight, said U.S. military officials. The deaths of Uday and Qusay Hussein, two of the most feared figures in their father's ousted regime, represent a major breakthrough for U.S. troops in Iraq, providing at least a temporary buoy to the spirits of demoralized soldiers. The U.S. had put a 15 US million dollars bounty on the sons and it will likely pay as much as 30 US million dollars to an informant who reportedly walked into the U.S. Centcom headquarters Monday evening and provided the tip on where the two were staying, in a region near the Syrian border. "This is a great day for the new Iraq," British Prime Minister Tony Blair said on a visit to Hong Kong. "It is a very, very important move forward and I think it is great news," he said. Although Bush and his senior officials have stated it would be more difficult to contain Iraqi resistance if Saddam and his sons remained at large, there is no definitive proof that attacks on Americans were being orchestrated by the sons or whether they are symptomatic of widespread resentment toward the occupying force. Gen. Ricardo Sanchez, commander of U.S. ground forces in Iraq, confirmed the deaths of the two men last night. Sanchez said in Baghdad the bodies of the two men were identified by multiple sources and more proof would be provided to skeptical Iraqis at a news conference today. "That is what we have stated over and over again. We remain totally committed to the Saddam regime never returning to power and tormenting the Iraqi people.'' The bodies are said to have been flown to Baghdad's international airport from the northern city of Mosul. The other two bodies were believed to be the teenage son of Qusay and a bodyguard. **Iraqi Resistance Kills 4 US Soldiers*** At least four US soldiers were killed yesterday in separate incidents, three in Mosul, one in Baghdad, Arab satellite channel Al-Jazeera reported. A US soldier was killed and another injured in an ambush along a dangerous road north of the capital Baghdad, the US military reported. The US Central Command in Tampa, Florida, said the attackers used rocket-propelled grenades and small arms in the attack staged along the road between Balad, some 80 kilometers north of Baghdad, and Ramadi, about 100 kilometers west of the capital, according to AP. Three killed US soldiers in Mosul are not mentioned in the US military report yet. **PHOTO CAPTION*** Undated file photo shows Uday Saddam Hussein during the invasion of Kuwait.
