WASHINGTON (Reuters) - U.S. military casualties have surged in Iraq in recent weeks, with U.S. troops engaging in perilous urban sweeps to curb sectarian violence in Baghdad while facing unrelenting violence elsewhere.

At least 44 U.S. troops have been killed so far in October. At the current pace, the month would be the deadliest for U.S. forces since January 2005. After falling to 43 in July, the U.S. toll rose in August and September before spiking this month. The war's average monthly U.S. death toll is 64.

The number of U.S. troops wounded in combat also has surged, with September's total of more than 770 the highest since November 2004, when U.S. forces launched a ground offensive to clear insurgents from Falluja.

Army Maj. Gen. William Caldwell, briefing in Baghdad on Thursday, attributed the rising casualties to insurgent violence that coincides with the current Islamic holy month of Ramadan, as well as more aggressive operations in Baghdad.

"We assume it will still get worse before it gets better. We expect violence to continue to increase over the next two weeks, until the end of Ramadan," Caldwell said.
