Troops have killed 12 suspected militants in operations in Swat valley, the army said Thursday. The first incident took place late Wednesday in Seigram village, about 25 kilometres (15 miles) northwest of Swat's main city Mingora, where security forces seeking a local insurgent commander stormed a Taliban hideout. "An exchange of fire took place resulting in the deaths of 10 miscreants and injuries to one soldier," the army-run Swat media centre said in a statement, adding that the militant commander was among those killed. Two other militants were killed in a shoot-out with security forces in Swat's Matta town on Thursday morning, the centre added.
