Suicide bombing in Pakistan military base kills 23

At least 23 people were killed in a suicide bombing at a Pakistan army base on Tuesday, an official said, in an attack claimed by militants affiliated with the Pakistani Taliban.

The early-morning attack targeted a base in Dera Ismail Khan district of Khyber Pakhtunkhwa province, near the Afghan border, according to a local official who spoke on condition of anonymity.

"Many of them were killed while they were sleeping and in civilian clothes so we are still determining if they are all military personnel," the official added.
