LAHORE, Pakistan (AP) — Pakistani officials say a passenger train has crashed into a bus carrying Sikh pilgrims at an unmanned railway crossing in eastern Punjab province, killing at least 22 people. Six pilgrims were also injured in Friday’s accident. Police say they transported the dead and injured to a nearby hospital. Officials said the pilgrims were from the northwestern city of Peshawar and were returning home from a visit to a shrine in the area. Sikhs have several shrines of their religious leaders in Pakistan. Train accidents are common in Pakistan, mainly due to lack of enforcement of safety standards, a poorly kept railroad system and negligence of drivers.
