JAKARTA: Officials say two Indonesian fighter jets have forced a Pakistani passenger plane to land after entering Indonesian air space without authorisation.

A spokesman for Pakistan International Airlines says the aircraft is chartered by UN peacekeepers in East Timor and might have strayed off course due to bad weather.

Local air force chief Agus Supriatna said the Boeing 737-300 with 54 people aboard landed Monday at the Sultan Hasanuddin airport in Makassar, the capital of South Sulawesi province. He said it would be allowed to leave after arranging necessary documents.

PIA spokesman Tajwar Mashood said that the Pakistani Embassy in Indonesia has been informed and is taking action.
