A bomb explosion on a passenger train in Pakistan left at least 17 people dead on Tuesday, NBCNews.com reported.
The blast was the result of a remotely-controlled bomb hidden in a bag on the Jaffar Express Train, according to police.
Police Chief Abdul Rehman said at least eight people were burned alive, noting one child and two women were among the killed.
"Fire engulfed the (carriage) following the blast causing most of the deaths," a rescue worker told Reuters.
Rehman said the train departed from Quetta and was headed to Rawalpindi. It had stopped at the Sibi Railway station in Balochistan when the bomb occurred.
Though Reuters reported that no one has taken responsibility for the attack, BBC News said the United Baluch Army (UBA) -- an armed separatist group -- admitted to the bombing.
Khawaja Saad Rafique, Pakistan's railway minister, said the same service was attacked a few days earlier but no one died.
"A few days ago terrorists fired upon a train when it came out of a tunnel [in Baluchistan), but they ran away when security forces responded to firing," Rafique said.
"We will have to review the security and find out the cracks from where the terrorists slipped in and planted the explosives."
On Monday, the Frontier Corps -- a unit of the Pakistan Army -- said they killed 40 militants in a fight against separatist groups in Baluchistan.
A spokesman for the UBA said Tuesday's bombing was a "revenge attack" for the army's offensive and warned of upcoming attacks within the next few days.
