KABUL, Afghanistan — A government official says two roadside mines possibly meant for later use against security forces have exploded in a residential area in Afghanistan's eastern Ghazni province, killing three children.

Arif Noori, spokesman for the governor of Ghazi province, said Friday that the mines detonated today in the remote Gilan district, killing three children and wounding seven others.

On Thursday night, Taliban attacks on security posts in Ghazni city killed two national police and wounded four others.

No one immediately claimed responsibility for the attack.
