Officials say there's been a fifth day of battles between Pakistani security forces and anti-Taliban militiamen against militants who crossed from Afghanistan.

A Pakistani military official says 11 militants and three security personnel were killed in fighting Tuesday in the Bajur tribal area in northwest Pakistan. The official spoke on condition of anonymity because he was not authorized to brief reporters.

A local government official in the Salarzai area of Bajur that is under attack, Jahangir Azam Wazir, said two militiamen and two civilians were also killed.

Another local official, Nazamin Khan, said many people are still stuck in villages in Salarzai where fighting has been most fierce.

The military said Monday that 31 militants, three security personnel and two militiamen were killed in the first four days of fighting.
