A train transporting 300 passengers has run off its railroad track, leaving at least 16 people dead and more than 100 others injured in Pakistan's southwestern province of Baluchistan.

"Four carriages of a Rawalpindi-bound train which left Quetta railway station were derailed near Abegum area of Bolan district, some 75 kilometers (46 miles) from Quetta city," Akbar Hussain Durrani, the Baluchistan home secretary, said on Tuesday.

The accident occurred near Quetta, the capital of Baluchistan Province, after the train's brakes failed as it came speeding down the side of a mountain, according to officials.

The train driver and his assistant, and two members of the railway police, are among the dead.

Train accidents frequently happen in Pakistan.

In July, at least 17 people were killed when a special military train fell into a canal after a bridge partially collapsed.
