The bomb exploded when nearly 100 passengers were waiting for a train to travel to the city of Rawalpindi from Quetta, the capital of the restive Balochistan province, said a senior police officer.
A suicide bomber blew himself up at a train station in restive southwestern Pakistan on Saturday, killing at least 24 people, including security officers, and wounding about 50 others, some critically, officials said.
The attack happened when nearly 100 passengers were waiting for a train to travel to the garrison city of Rawalpindi from Quetta, the capital of the restive Balochistan province, according to Hamza Shafqaat, a senior government administrator.
A separatist group, the Balochistan Liberation Army, claimed the attack in a statement, saying a suicide bomber targeted troops present at the railway station. The outlawed BLA has long waged an insurgency seeking independence from Islamabad.
Police said about a dozen security forces are also among the dead.
