PESHAWAR (AFP) - At least five people were killed when militants fired on two vehicles in northwest Pakistan on Saturday, officials said. Five people died and 11 others were wounded when militants fired on the two vehicles in the northwestern Jawakai tribal area, some 50 kilometres east of Peshawar, senior government official Sahibzada Mohammad Anis told AFP. Regional police chief Mohammad Masood Khan Afridi confirmed the shooting and deaths, and said it was the work of militants. There was no immediate claim of responsibility for the attack, in a region rife with a homegrown insurgency. No group has claimed responsibility for the attack. Taliban and Al-Qaeda-linked militants frequently launch attacks on vehicles specially those carrying supplies for Nato forces. Most supplies and equipment required by foreign forces in Afghanistan are shipped through Pakistan, although US troops increasingly use alternative routes through Central Asia.
