A Qantas plane has made an emergency landing at Singapore airport, Indonesian authorities say.
Indonesian media reports today said there had been some sort of explosion over the Indonesian island of Batam, near Singapore, about 9.15am local time.
Tatang Kurnia, head of Indonesia's Transportation Safety Board, said the explosion came from a Qantas plane that had just lifted off from Singapore.
"We've been informed from Singapore that a Qantas plane overflying the area defuelled and then made an emergency landing back in Singapore,'' he told MetroTV.
Qantas says the plane, flying from Singapore to Sydney, experienced engine problems.
"Qantas flight QF32 was enroute from Singapore to Sydney, the number two engine has shut down, so as a precautionary measure we are taking it back to Singapore,'' A Qantas spokeswoman told AAP.
Indonesian media reports said debris from the plane had landed in downtown Batam.
Pictures on local television appeared to show the Qantas logo on some of the debris.
Comment was being sought from Singapore's Changi airport.
