Indonesian officials say Sriwijaya Air jet lost contact with air traffic controllers after taking off from Jakarta.

Both the Indian shuttlers are expected to overcome their respective first-round opponents -- Aya Ohori for PV Sindhu and Sayaka Takahashi for Saina Nehwal -- and cross swords in what would be their fifth encounter at the international stage

Around a dozen people were still unaccounted for after record rains that started on New Year's Eve pounded Jakarta and left swathes of the megalopolis, home to some 30 million, under water and with thousands homeless.

Jakarta, first established by Dutch colonists nearly 500 years ago, is one of the fastest-sinking cities on earth

Decades of uncontrolled and excessive depletion of groundwater reserves, rising sea-levels, and increasingly volatile weather patterns mean swathes of it have already started to disappear.

The government had deployed some 50,000 police and soldiers in Jakarta, in anticipation of protests following the official election results.

The idea of moving Indonesia's seat of government from an urban conglomeration of nearly 30 million people with some of the world's worst traffic jams has stretched on for decades.

The Spanish shuttler was leading 10-4 before her discomfort and pain made her pull out of the mega final.

The 28-year-old Indian, who was a runner-up here last year, notched up a 18-21 21-12 21-18 win over sixth seed Bingjiao, a world championship bronze medallist.

Srikanth, however, had to settle for a second quarterfinal finish after losing 18-21 19-21 to local hero and Asian Games champion Jonatan Christie.

The 305-metre-high volcano, about 200 kilometres southwest of capital Jakarta, has been erupting since June. In July, authorities widened its no-go areas to 2 kilometres from the crater.

A total of 188 passengers and crew were aboard the plane that took off from Jakarta and vanished minutes later.

Another Lion Air plane was involved in an accident where it smashed into a pole during take-off in Indonesia.

The directive instructs airlines to make specific changes to flight manual procedures for responding to the problem.
