At least 20 people were killed and 150 injured in Pakistan after five bogies of a Rawalpindi-bound train derailed in Bolan, Balochistan, local reports said.

The train was travelling from Quetta to the garrison city of Rawalpindi, a local report said. The train driver was among those killed, reported the Associated Press.

According to Geo TV, there a total of 300 passengers in the train. The army has been deployed in the region. Videos from the accident site show rescue personnel dragging out the injured and the dead from the mangled remains of the passenger train.

Train accidents are a common occurrence in Pakistan, due to poorly maintained tracks and bridges, besides drivers often disregarding speed limits, noted a report in Pakistani website Dunya News.

Five months ago, at least 15 military  personnel were killed after a special train carrying troops and military equipment fell from the Chanawan Bridge in the eastern province of Punjab.

More details of Tuesday's accident are awaited.
