Two children were killed on Tuesday in a mortar attack by suspected Al-Qaeda activist on a military check-post in a remote tribal village near Afghan border, officials said.
"Two boys were martyred after mortars fired by miscreants hit them in Khamrang village," ISPR spokesman, Major General Shaukat Sultan told AFP.
The activist missed the target and mortar shells landed away from the military post in Khamrang village near Wana.
Security forces and militants have been trading fire in the area since last week.
The exchange of fire has continued since the army wrapped up a major operation in the Shakai valley in the middle of June, after killing 65 foreign militants and their local supporters.
Some 18 troops were also killed in last month's operation, during which the army said it dismantled an al Qaeda training camp and hideouts.
