Two US soldiers were killed Monday morning by a grenade that was thrown on an American military patrol in central Baghdad. Local eyewitnesses said the two troops have died after a man dropped a grenade on their vehicle from a road bridge at an intersection in broad daylight. Meanwhile, General Richard Myers, the chairman of the U.S. Joint Chiefs of Staff, said Sunday that following the deaths of Saddam Hussein's two sons, he is sure the ousted Iraqi leader will be found. Speaking on arrival in Baghdad, Myers said there has been a big increase in the number of informants coming forward, providing evidence of weapons caches and the locations of Iraqi officials. He expressed confidence it is only a matter of time until Saddam is captured. "If he is alive, it is just a matter of time and again, our belief is that he is not having a major effect on what is going on right now," said Myers. "He is so concerned with survival. He has been through these survival modes before. He knows how to do that but we will find him. It is a big country but we will find him." ** Five Iraqi Civilians dead in Fruitless US Hunt for Saddam*** In Sunday, US soldiers hunting Saddam Hussein have killed five Iraqis and wounded eight more.
