Six soldiers and 25 insurgents were killed Wednesday in clashes in Pakistan's tribal region near the Afghan border, a security official said. The fighting started in the Bara area of the Khyber tribal district when a group of 50 to 60 militants attacked a security post with rocket-propelled grenades, assault rifles and suicide car bombs, according to a report of the German Press Agency "DPA". A statement from the paramilitary Frontier Corps said the troops destroyed several suicide car bombs during the clashes, which lasted for hours. At least six soldiers were killed and 15 were injured in the attack, the statement said. Twenty-five rebels also died as the security forces repulsed the attack and later targeted several of the militants' positions with artillery fire, the corps said.
