At least five people were killed and about 30 or more injured when the Peshawar-bound Rehman Baba Express derailed near Sher Shah station in Multan district, in Pakistan's Punjab province, on Tuesday; the cause has not been officially established and an investigation has been ordered. Rescue teams took the injured to hospital, and the railways minister promised compensation and medical care. The crash adds to a string of derailments over the past year that have raised concerns about the state of Pakistan Railways' tracks and maintenance.
