Pakistani officials say that more than 100 Taliban fighters crossed over from Afghanistan and attacked three Pakistani military posts on June 24, killing at least six soldiers.
Military officials say at least 11 of the attackers were also killed in the firefight, which lasted 40 minutes in the Soni Darr area of Upper Dir district.
A Taliban spokesman, Saruj ul-Haq of the Tehrik-e-Taliban Pakistan (TTP) in Malakand area, took credit for the attack in a phone call to Radio Mashaal.
The attacks were the latest in a series of cross-border assaults from regions in eastern Afghanistan where U.S. troops began pulling out last year.
