Pakistani security officials say more than 200 people are being questioned after a Pakistani passenger plane was shot at.
One woman was killed and two injured when attackers fired bullets at the Pakistan International Airlines plane just before landing at Peshawar's international airport late on June 24.
The plane, with 178 passengers on board, was flying from Riyadh in Saudi Arabia.
No one claimed responsibility for the attack, but authorities suspect the Pakistani Taliban.
Police spokesman Najibur Rehman was quoted by the dpa news agency as saying more than 200 people were being questioned after being detained on June 25 in and around the airport.
The attack follows a major Taliban assault on the airport in the southern Pakistani city of Karachi earlier this month.
