BAGHDAD, Iraq (CNN) -- The Mosul leader of al Qaeda in Iraq was shot to death by Iraqi soldiers during a combat operation in the northern Iraqi city Wednesday, a U.S. military statement said.
U.S. and Iraqi troops have been taking on militants in the Baquba area and throughout Diyala province
It comes as the U.S. records its lowest monthly troop death toll since November, reflecting military hopes that the recent military buildup is making strides.
Iraqi soldiers spotted al Qaeda's emir of Mosul -- known as Safi -- riding in a pickup truck in northeastern Mosul and began chasing his vehicle, the military said in a statement released Thursday.
After pulling over, Safi and two bodyguards emerged from the truck and opened fire on the soldiers, but they were shot dead, the military said.
"The death of Safi will further disrupt senior AQI leadership in Mosul, which has been unstable since May, due to the combined efforts of Coalition Forces and ISF (Iraqi security forces) offensive operations," said U.S. Army Col. Stephen Twitty, commander of 4th Brigade Combat Team, 1st Cavalry Division.
Meanwhile, a suicide bombing targeting a police station in Iraq's volatile Diyala province on Thursday has killed five people and wounded seven others, the Interior Ministry told CNN.
Police and civilians were among the victims in the incident, which took place in the town of Hibhib.
On Tuesday, six U.S. soldiers were killed in Iraq, bringing the total death toll for July to 79, the lowest figure since November.

Two Task Force Marne soldiers were killed and 10 were wounded in an indirect fire attack Tuesday, the military said on Thursday.
Three U.S. soldiers were killed and six wounded when a bomb exploded near their combat patrol in eastern Baghdad, the military said on Wednesday.
The bomb was the type known as an explosively formed penetrator, which the military said is a more powerful and sophisticated version of a roadside bomb.

A soldier "was killed by small arms fire during combat" in eastern Baghdad on Tuesday.
