Further disintegration in Iraq

From Thursday's Washington Post:

BAGHDAD, Oct. 18 -- A roadside bombing and other attacks killed 10 American troops across Iraq on Tuesday, the U.S. military reported Wednesday, making it the deadliest day of combat for U.S. forces in 10 months.

The one-day toll, part of what the U.S. military has said is a 43 percent increase in attacks on U.S. and Iraqi forces in the capital since midsummer, occurred as casualties among Iraqi troops and civilians are soaring far higher than at any previous time in the war, according to U.S. and Iraqi tallies.

The deaths underscore the surging nature of sectarian violence and the increasing lethality of roadside bombs, which claim the most American lives in Iraq despite efforts to bolster armor and use high-technology devices to disable bombs.

Five of the American troop deaths Tuesday were caused by bombs. Four soldiers were killed in Baghdad about 6:50 a.m. when a planted bomb exploded under their vehicle, the U.S. military said in a statement. Another bomb killed a single soldier north of the capital.

Three soldiers died in combat east of Baghdad, in Diyala province, the military said. One soldier was killed in north Baghdad when armed men attacked his patrol, and a Marine died in combat in the predominantly Sunni province of Anbar, in western Iraq. Since the summer, Baghdad has passed Anbar as the most hostile place in the country for U.S. and Iraqi forces.

Tuesday's deaths, along with the death of an American soldier in Baghdad by small-arms fire on Wednesday, brought the number of total U.S. troop fatalities for October to 70, including 67 killed in action......
