Kabul, Afghanistan (CNN) -- At least 11 civilians were killed Saturday in a roadside bomb attack in Afghanistan's southern Zabul province, a local police official said.
"Women and children are among the deaths, too. These people were on the way going to Pakistan from Zabul province, said Ghulam Nabi Elham, Zabul police chief.
Elham said he thinks the device was planted to target Afghan forces in Zabul.
President Hamid Karzai and NATO's International Security Assistance Force condemned the attack.
"Those responsible for this heinous act showed that their pursuit of power is more important to them than the sanctity of human life," ISAF spokesman Rear Adm. Vic Beck said.
In western Afghanistan, an international service member died in a bombing on Saturday, and ISAF confirmed reports that the service member was an Italian soldier killed in Farah province.
