ISLAMABAD: At least 15 people were killed and 50 injured as 10 bogies of Rawalpindi-bound Hazara Express derailed near Sahara Railway Station, 275 km near Karachi on Sunday, local media reported.

Ten bogies had gone off track in the train crash, Railways Divisional Superintendent Sukkur Mahmoodur Rahman was quoted as saying by Geo TV.

The injured were shifted to the People's Medical Hospital in Nawabshah.

Rescue efforts are underway to pull out passengers from the affected bogies. A train is arriving at the site of the incident from the Loco Shed Rohri. It will take at least three hours to reach the site, Rahman said.
