A pair of bomb attacks in northern Iraq late Tuesday killed three American soldiers and an interpreter and wounded at least 90 Iraqis.

The bombings — one in Mosul and another at an unspecified location in Nineveh province — brought the number of Americans killed in Iraq since Monday to at least nine. Four Americans — including two civilians working for the Defense Department and State Department — were killed earlier Tuesday in a bombing in Sadr City, while two others were killed Monday in a shooting southeast of Baghdad.

At least 25 American servicemembers have been killed in Iraq in June, compared to 19 in May, according to, which tracks casualty figures in the Iraq and Afghanistan wars.

The Tuesday attack targeting U.S. troops in Nineveh province was a roadside bomb, officials said. The explosion occurred around 10:45 p.m.

Little other information about the incident was available on Wednesday.

The other attack was described as a car bomb, which struck near a coffee shop and other buildings in Mosul. U.S. officials have said that Mosul is the last urban stronghold for al-Qaida in Iraq. A short statement released Tuesday blamed the Mosul attack on that group.

"This is yet another example of AQI’s indiscriminate targeting of innocent civilians and their lack of value on life," Maj. Patrick Conway, a spokesman for Multi-National Division-North said.

Mosul has a population of around 2 million people. Some 14 Iraqi army battalions, along with 10,000 Iraqi police and 4,000 U.S. soldiers, are responsible for security there.

The city is a mix of Arab, Kurd, Christian, Turkoman and other populations.
