At least 13 people have been injured after a bomb blast derailed a passenger train in the southwestern Pakistani province of Balochistan.

The bomb exploded after midday (07:00 GMT) on Friday as the Jaffar Express passenger train was passing through the Bolan district,

more than 150 kilometres (more than 90 miles) from the provincial capital Quetta, authorities said. The train was travelling to Peshawar, the capital of the northwestern province Khyber Pakhtunkhwa.

The explosion derailed eight train cars, including the engine. At least 13 injured after a bomb attack derails a train in Bolan district in Balochistan province, local official says.

Balochistan Chief Minister Mir Abdul Quddus Bizenjo in a statement condemned the attack and ordered the local administration to provide immediate rescue services.

Balochistan is Pakistan’s largest province and has the highest poverty rate in the country. The region is also the hub of a decades-old separatist movement.

The rebels have been fighting the government for decades, demanding a separate state and saying the central government unfairly exploits Balochistan’s rich gas and mineral resources.
