A passenger plane with more than 50 people on board has gone missing after take-off from the Indonesian capital, Jakarta.

The Sriwijaya Air Boeing 737 lost contact en route to Pontianak in West Kalimantan province, officials said.

Flight tracking website Flightradar24.com said the aircraft had lost more than 3,000m (10,000ft) in altitude in less than a minute.

The Transport Ministry said search and rescue efforts were under way.
