BAGHDAD - Six more US soldiers have died in separate incidents in Iraq, the military said Wednesday.
Four US army soldiers were killed or fatally wounded by "explosions near their vehicles" in the Diyala province, north of Baghdad, on Wednesday.
Also, a soldier was shot Tuesday while his unit was providing security at the site of a homemade bomb found north of Baghdad, and died Wednesday, a military statement said.
On Tuesday, a soldier died near Tikrit, Saddam Hussein's hometown north of the capital, "in a non-combated related incident, which is currently under investigation," a separate statement said.
The deaths brought US military fatalities in Iraq since the March 2003 invasion to 3,122, according to Pentagon figures.
Meanwhile, a suicide car bomber attacked an Iraqi police station in the western city of Ramadi, killing 11 people including four police, the US military said Thursday.
Wednesday's attack also wounded 21 people, a spokesman said.
Iraqi medical and security sources in the city, a hotbed of Sunni insurgents, said the police station was severely damaged in the blast.
They said the local police chief was among those killed, but that was not confirmed in the US statement.
Iraqi security forces are a constant target for insurgent fighters trying to undercut the Shiite-dominated unity government of Prime Minister Nuri al-Maliki.
