General says toll will grow as more forces deploy in security plan. Eight Americans die in three separate attacks. BAGHDAD A U.S. Army general on Sunday warned that American casualties would rise in the coming months, a prediction underscored by the deaths of six soldiers and a foreign journalist in a roadside bombing north of Baghdad. Five other American troops died elsewhere over the weekend. Maj. Gen. Rick Lynch, commander of the 3rd Infantry Division, said casualties would climb as American troops went deeper into enemy territory as part of a stepped-up military operation ordered by President Bush in January. Lynch, who oversees a swath of territory to the south and east of Baghdad, gave his bleak prediction on the heels of the deadliest month so far this year for American forces in Iraq. In April, 104 U.S. troops were killed, only the fourth time since the beginning of 2005 that U.S. deaths have exceeded 100 in a single month. At least 25 troops have been killed so far in May, a grim start to a month in which Democrats are expected to keep up pressure on the White House to plan a withdrawal from Iraq. At least 3,376 American troops have been killed since the U.S.-led invasion in March 2003, according to the website icasualties.org, which tallies casualties. The latest American deaths came on a bloody day for Iraqi security forces and civilians as well. At least 58 Iraqis died in a string of attacks, including 42 killed when a car bomb tore through a market in the Baghdad neighborhood of Bayaa. North of the capital, in Samarra, 12 police officers died when a suicide bomber rammed a car into the police headquarters. Witnesses said scores of vehicles filled with people waving black flags representing the Islamic State of Iraq, an Al Qaeda-linked Sunni Arab insurgent group, cruised menacingly through the city before the attack. The occupants fired on police stations, killing one officer before the car bomber struck. Samarra's police chief, Col. Jaleel Nahi Hassoun, was killed in the blast. In February 2006, Sunni insurgents destroyed Samarra's Golden Mosque, one of Shiite Islam's most important shrines, in an attack that unleashed fierce sectarian warfare. http://www.latimes.com/news/nationworld/world/la-fg-iraq7may07,0,3673790.story?coll=la-home-world How much longer and how much worse before it gets better?
