ISLAMABAD, Oct. 7 (Xinhua) -- At least eight people were killed and 19 others injured when two bombs hit a passenger train in Pakistan's southwest Balochistan province on Friday, local media and offcials said.

The Federal Minister for Railways Khwaja Saad Rafique said the passenger train Jafar Express was targeted by a remote-controlled device in Mach area of Balochistan, some 50 km northeast of the provincial capital of Quetta.

Railway authorities said the train was on its way to the northern Rawalpindi city from Quetta when it came under attack.

Local Urdu TV channel Dunya said the first blast hit two compartments of the train and as soon as the rescue teams gathered at the site, the second explosion happened.

The report added the killed people included two security personnel and a government official.

All the injured have been shifted to Quetta via army hellicopters, where an emergency has been declared at all state-run hospitals.

No group has claimed responsibility for the attack yet, but Rafique said there is a group in Balochistan who is involved in targeting railway tracks and trains, however he did not mention the name of the group.

The minister said a suspect has been arrested at the blast site.

Police cordoned off the area for further investigations.
