Army spokesman Akhtar Abbas said, "Soldiers looking for militants after a suicide bombing encountered resistance in several areas and that battles raged into the early morning Monday, Aug 31."
The military has said it is restoring security in the valley after a three-month operation to retake control of areas overrun by Taliban militants.
A suicide bomber on Sunday sneaked into a police courtyard in the valley's main town and killed 17 cadets while they were training. The attack was the deadliest since the military regain control of most of Swat in July.
On Sunday, Aug 30, at least 15 security personnel were killed and several others injured in a suicide attack on a police station in Pakistan's northwestern Swat Valley.
