Mansoor Dadullah, who was captured near the border with Afghanistan, is the brother of Taliban leader Mullah Dadullah, who was killed in southern Afghanistan last May by coalition forces, CNN reported.

Four more militants were captured near the Gaddal post in the province's Qila Saifullah town, the report said quoting Pakistani military spokesman Lt. Col Baseer Haider Malik.

The spokesman said the group was seeking to enter Pakistan from Afghanistan. A fifth militant was killed, the military said.
