A suspected suicide bombing killed at least 11 people and injured more than 20 others at a police checkpoint in northwestern Pakistan Tuesday, media reports cited officials. Authorities reportedly said the death toll from the bombing, which targeted the police, was expected to rise.

The attack reportedly took place on the outskirts of Peshawar, a city in Pakistan's Federally Administered Tribal Areas, where security forces are fighting the Pakistani Taliban and other militant groups near the border with Afghanistan, two senior government officials said, according to Reuters. The bomber reportedly rammed his motorcycle into a roadside police checkpoint.

"He was riding an explosives-laden motorcycle and hit the checkpoint and the vehicle of the line officer," local government official Munir Khan told Reuters.

Authorities reportedly said the wounded were taken to a hospital in Peshawar. A spokesperson at the Hayatabad Medical Complex in Peshawar reportedly said that one of the bodies they received following the blast was of a child. The dead also included policemen and civilians.

No group has claimed responsibility for the attack so far.
