BAGHDAD, July 18 (AFP) - A US soldier was slightly injured in a roadside bomb blast in southeast Baghdad on Sunday morning, a military spokesman said.
"There was one minor injury but no damage to equipment," he said, without being able to give further details on the blast.
Several loud booms were heard later in the day around the city but it was not immediately clear what caused them.
Baghdad is frequently rocked by explosions largely caused either by insurgents or controlled detonations of munitions from Saddam Hussein's deposed regime.
