At least 30 people have been killed and 100 injured when a train derailed in southern Pakistan, a police spokesman has confirmed.
Several carriages of the Hazara Express overturned near Sahara railway station in Nawabshah, about 171 miles from the largest city Karachi.
Wounded passengers were moved to nearby hospitals. Rescue teams are trying to free people from the twisted wreckage.
Railway Minister Saad Rafiq said initial investigations showed the train was travelling at normal speed and they were trying to establish what led to the derailment.
A railways spokesperson in Karachi said at least eight carriages went off the track.
Some people were still trapped inside a train carriage, according to local broadcaster Geo.
An emergency has been declared in the main hospitals in Nawabshah and neighbouring districts of Sindh.
Videos posted on social media show dozens of people at the site of the accident, with some passengers climbing out of the overturned carriages.
Train services to the interior districts of Sindh have been suspended.
