Five more US soldiers have been killed in attacks and fighting with rebels in Iraq, the American military announced on Tuesday, bringing the death toll for the month of October to 91.
One soldier died on Tuesday "from wounds he received when his patrol was struck by an improvised-explosive device in central Baghdad", it said.
In the western province of Al-Anbar, two marines and a sailor died on Monday of injuries "due to enemy action", the military said in a separate statement.
The military had earlier said that an army soldier was killed on Sunday by a roadside bomb in Baghdad, bringing the number of dead over the weekend to 12.
If the toll continues to mount at the same rate until the end of October it will become the deadliest month for US forces in Iraq since November 2004, when they famously fought fierce street battles in the western town of Fallujah.
At least 2,797 members of US forces have been killed or died accidentally in the Iraq campaign since the March 2003 invasion, according to an AFP count based on Pentagon figures.
