The bombs hit the Jaffer Express which runs between Quetta and Rawalpindi, next to the capital, Islamabad.
The terrorist attack was claimed by the separatist Baloch Liberation Army (BLA) and aimed at targeting military personnel travelling to Rawalpindi. The Pakistani military is accused of committing widespread abuse in the fight against the insurgents, which it denies. Speaking from an undisclosed place, the spokesperson of BLA, Jeeyand Baloch said that the army will continue to deploy the guerrilla warfare tactics in order to end the occupation.
Balochistan Chief Minister Nawab Sanaullah Zehri strongly condemned the attack and expressed great sorrow over the loss of precious lives during the blasts. He prayed for early recovery of the injured and directed the authorities to take all the possible measures and steps to arrests those involved in this inhuman act.
Attacks on infrastructure in Balochistan are a cause of concern for Pakistan's neighbour and "all-weather" friend China, as Beijing is investing $46 billion in the China-Pakistan Economic Corridor project, which aims to link western China to Pakistan's Arabian Sea with a network of road, rail and energy pipelines. Many of the routes pass through Balochistan.
