Militants detonated a bomb outside a police station in the northern Iraqi city of Mosul today as a US convoy drove past, killing two soldiers and wounding two more.
Police who witnessed the attack said the bomb exploded as four US soldiers drove past in two civilian vehicles.
"There was a huge blast. The two drivers of the vehicles were definitely killed," said a policeman, who witnessed the explosion, his face spattered with blood.
The 101st Airborne Division, in charge of security in Mosul, confirmed that two soldiers had been killed and two wounded.
The attack raised to 120 the number of US soldiers killed in Iraq since major combat was declared over on May 1st - more than the 114 killed in action in the war in March and April.
Many Iraqis are on edge due to widespread talk that today has been declared a "day of resistance" by forces fighting the US occupation and that several major attacks are planned.
The United States blames loyalists of ousted Iraqi President Saddam Hussein and foreign Islamic militants for the attacks.
