ISLAMABAD - A suicide bomber rammed his motorbike into a checkpoint near the Pakistani military's headquarters on Monday, killing 10 people including soldiers, police said.
The attack in the garrison city of Rawalpindi, just south of the capital Islamabad, killed at least seven soldiers, said police official Mian Maqbool.
More than 20 people, including children, were injured in the bombing, he said.
Pakistani Taliban claimed responsibility for the blast and vowed more attacks on security forces.
"We did this and will continue our mission against the army," said Taliban spokesman Shahidullah Shahid.
Islamist militants based in Pakistan's lawless tribal regions near the Afghan border have recently stepped up their campaign against security forces.
Monday's fatal bombing comes a day after Taliban blew up a vehicle being used by the military in the country's troubled north-west, killing 20 security personnel.
Prime Minister Nawaz Sharif and his cabinet were scheduled to hold a meeting on Monday to decide how to respond to the militant violence.
