The authorities in a semi-autonomous tribal area near Pakistan's border with Afghanistan have seized 22 anti-aircraft missiles from a village.
The assistant political agent in the Kuram Agency tribal area, Kifayatullah Khan, told reporters that the seizures were made following a tip-off from local villagers.
He said the missiles had been stored by an Afghan national, who came from the eastern Afghan province of Paktia, and is now being sought by police.
A BBC correspondent in the area says Pakistan's tribal areas bordering Afghanistan are awash with all kinds of weapons, and such seizures are common.
