At least five people were killed and 16 others injured on Monday in a bomb blast in Quetta-bound Jaffar Express train in southwest Pakistan.
The train, which departed from Rawalpindi, was passing through Dera Murad Jamali district of the restive Balochistan province when the blast occurred causing damage to at least four bogies of the passenger train.
Media reports had earlier suggested that it was a suicide attack but state-run Radio Pakistan said it was a remote control bomb blast.
Emergency and rescue team were dispatched to the site.
Security personnel reached the site and cordoned off the area as a probe into the incident went underway.
On August 15, suspected militants attacked a Rawalpindi- bound passenger train with rockets in Bolan district, killing at least two persons and injuring 32 more.
