A passenger plane has crashed at Tripoli airport, killing more than 100 people on board, Libyan officials say. The Afriqiyah Airways flight from Johannesburg had been due to land at 0400 GMT. The plane crashed as it attempted to land, the airline said. Officials say 93 passengers and 11 crew were on board the Airbus 330. They are said to be of various nationalities, including British and South African. The plane had been due to go on from Tripoli to London's Gatwick airport. Unconfirmed reports say that an eight-year-old child was the sole survivor of the crash. The 11 crew member were all thought to be Libyan nationals, an employee said. Afriqiyah Airways later said on its website that Flight 8U771 had an accident during landing at Tripoli airport. "At this moment we have no information concerning possible casualties or survivors," it said. Britain's Foreign and Commonwealth Office said said it was "aware of reports that there were British nationals on board the flight, but this has not been confirmed".

The BBC's Rana Jawad in Tripoli says it was not clear whether the plane was on the runway when it crashed, but she says that people she spoke to at the airport said they could not see the plane. Our correspondent says that the airport is currently sealed off and ambulances have been going back and forth to the airport. She adds that the weather has been sunny and clear over the past few days. Afriqiyah Airways is a Libyan airline that was founded in 2001.
