NATO officials have told the Associated Press that three United States soldiers were killed by a roadside bomb in the Zhari disctrict of Kandahar province, Afghanistan on Tuesday.
Spokesperson Colonel Thomas Collins said that an explosive hidden in a parked motorcycle tore through a busy marketplace during its weekly bazaar in southern Afghanistan.
"The convoy struck an IED (improvised explosive device) in Zhari district this afternoon," he said.
Initial reports said that at least three people were killed, with seven more wounded.
They then reported that four U.S. service personnel died. But officials have updated their information concerning the incident, and confirmed that three have passed.
Collins also said that a handful of people are wounded, but did not confirm, nor deny the previously reported number of seven injured.
According to a spokesperson for the province's governor, Omer Zawak, four of the wounded are children. Two of them are in critical condition.
The bomb hit a market in the village of Safar, located about 40 miles from the province Helmand, where many members of the area's Taliban reside.
AP called the location a "volatile" one, where stand-offs between local government, dissidents and American soldiers stationed there happen frequently.
The violence has escalated since Monday, when three Georgian soldiers were killed by yet another bomb hidden in a truck by the gate of their outpost.
The wounded soldiers are currently in stable condition in a military hospital.
Later that day, in the northern province of Kapisa, a suicide bomber hit a United States Special Operation Forces procession.
NATO spokesperson Major Bryan Woods said that the attacker slammed his vehicle into the US Forces' convoy.
No one was harmed from the crash.
Woods said that the United States forces "engaged the enemy," then returned to their base.
12 members of the US army have died in Afghanistan so far this month.
