Two explosions on a passenger train killed at least six and wounded 19 others in Pakistan's Balochistan province today, international news agency AFP reported.
The attack was claimed by the Baloch Liberation Army, according to reports.
An army spokesman said the attack had targetted "military personnel who travel to Rawalpindi by this train".
"The explosions damaged two passenger carriages and killed six people besides wounding 19 others," senior local Pakistan Railways official Imtiaz Ahmad told AFP, updating the earlier toll of three deaths.
He said the fresh toll came after railway officials finalised the list of dead and injured. It was also confirmed by a senior doctor at the local hospital Noor Baluch.
The Rawalpindi-bound Jaffer Express was crossing the town of Much, 55 kilometres east of Balochistan's capital Quetta.
Initial reports suggested that a bomb was planted along the railway track in the Ab-e-Gum area of Balochistan's Bolan district, Pakistani daily, The Dawn, reported.
"There was another blast after the first one with an interval of 20 minutes at the same spot," Hameed Gul, a senior railway official, was quoted as saying by The Dawn.
Provincial home secretary Akbar Harifal also confirmed the incident and number of casualties. "We have rushed the rescue teams to the accident site," he said, adding the identity of the passengers was not immediately clear, AFP reported.
Meanwhile, Pakistani Prime Minister Nawaz Sharif "strongly condemned the attack and directed authorities concerned to find the culprits and bring them to task immediately," an official statement said.
