LAHORE - Bomb alerts forced two PIA planes Wednesday to land at Istanbuls Ataturk airport and in Kuala Lumpur. PIA official said security officials with sniffer dogs searched the Boeing 777-300EA in Istanbul, which had 378 passengers on board. The passengers were evacuated from the aircraft, which was moved to a security zone. The plane had departed from Lahore for Manchester. In Malaysia, a Pakistani passenger jet with 187 people on board landed in Kuala Lumpur at 9:24 pm (1324 GMT) following a bomb alert, but a search of the aircraft found no explosive devices on board, officials later said. According to our people on the ground, the plane has been searched and they have not found any bomb, it appears to be a hoax, a PIA spokesman said. A senior PIA official confirmed the two bomb threats. We received emails about the presence of bombs on two PIA flights. Since the flights had taken off already, the pilots were directed to land at the nearest airport.
