Railway officials told BBC Urdu that the explosion caused three carriages and the engine to derail, with two carriages overturning. The shuttle train was carrying military personnel and their families returning home for Eid holidays. A massive explosion occurred at that time.

The separatist group Balochistan Liberation Army (BLA) has claimed responsibility for the attack. The armed group, which has been demanding independence for decades, said its members carried out a suicide bomb attack on the train targeting soldiers and their families. However, government officials have not yet confirmed the BLA attack.

Images from the scene showed burnt and mangled carriages, damage to several nearby vehicles, and a building hit by the blast. Local resident Nasir Ahmed told the BBC that the explosion occurred while the train was moving and passengers were inside.
