ISLAMABAD: A suicide bomber blew himself up close to a police checkpoint in northwestern Pakistan on Tuesday, killing at least ten people and wounding more than 20, officials said.

The suicide bomber rammed his motorcycle into the roadside checkpoint in the Jamrud area of Pakistan's volatile Federally Administered Tribal Areas, local government official Munir Khan told Reuters.

"He was riding an explosives-laden motorcycle and hit the checkpoint and the vehicle of the line officer," Khan said.

Among the dead were at least five police officers including the line officer whose vehicle was targeted by the bomber, and a journalist, officials said.

A spokesperson for the Hayatabad Medical Complex in Peshawar, to where the wounded were evacuated, said earlier that the hospital had received six bodies, including that of a child.

No one has claimed responsibility for the blast.

Last month, a suicide bomber attacked a government office in northwestern Pakistan, killing at least 23 people.
