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.
It went missing shortly after 14:40 (8:40 CET).
A statement released by the airline said the plane was on an estimated 90-minute flight with 56 passengers and six crew members on board.
A search and rescue operation was underway in coordination with the National Search and Rescue Agency and the National Transportation Safety Committee, Irawati said in a statement.
Local media reports said fishermen spotted metal objects floating in the sea in the Thousand Islands, a chain of islands north of Jakarta, on Saturday afternoon but it has not been officially confirmed to be debris from the missing aircraft.
Television footage showed relatives and friends of people aboard the plane weeping, praying and hugging each other as they waited at Jakarta’s airport and Pontianak’s airport.
Indonesia, the world’s largest archipelago nation, with more than 260 million people, has been plagued by transportation accidents on land, sea, and air because of overcrowding on ferries, aging infrastructure, and poorly enforced safety standards.
In October 2018, a Boeing 737 MAX 8 jet operated by Lion Air plunged into the Java Sea just minutes after taking off from Jakarta, killing all 189 people on board. It was the worst airline disaster in Indonesia since 1997 when 234 people were killed on a Garuda flight near Medan on Sumatra island. In December 2014, an AirAsia flight from Surabaya to Singapore plunged into the sea, killing 162 people.
Sriwijaya Air is one of Indonesia’s discount carriers, flying to dozens of domestic and international destinations.
