At least 11 people have been killed and 20 others wounded as a speeding passenger bus collided with a parked long trailer on a highway in central Pakistan where heavy fog limited visibility, police say.
Talat Mahmood, a local motorway police official says the accident occurred on Thursday near the town of Khanewal, about 50 kilometers (30 miles) southeast of the city of Multan in the Punjab province.
Thick fog has enveloped parts of Pakistan in recent weeks, contributing to several accidents, reports the Associated Press.
Deadly road accidents are common in Pakistan, where motorists often disregard traffic laws.
