Nine Dead, Thousands Caught in Severe Flooding in Jakarta on New Year's Eve

Jakarta: Nine people died after Indonesia's capital was hit by its deadliest flooding in years, authorities said Wednesday, as torrential rains on New Year's Eve left vast swathes of the megalopolis submerged.

Electricity was switched off in hundreds of waterlogged neighbourhoods across greater Jakarta, home to about 30 million people, with some train lines and one of the city's airports also shut.

A 16-year-old was electrocuted by a power line, while three more people died of hypothermia said Jakarta disaster management agency head Subejo.

"We're hoping that the floodwaters will recede, but if the rain keeps up it'll continue," said the official, who like many Indonesians goes by one name.

Among the victims was an elderly couple trapped inside their home in a district where floodwaters reached as high as four metres (13 feet) after a river burst its banks.

Another victim drowned while four people were killed after the Tuesday evening downpour triggered landslides in the city's outskirts.

"We have shut down power (in many areas) to avoid more electrical shocks," Ikhsan Asaad, an official at state firm PLN, told AFP.

Asaad said he could not estimate how many residents had been affected by the power shutdown.

"We're currently focusing on taking measures to ensure people's safety," he added Authorities said about 13,000 people were evacuated, but that figure did not include residents in Jakarta's satellite cities.

"We're evacuating people right now," Jakarta governor Anies Baswedan told reporters.

"Everyone living near rivers should anticipate (more) flooding," he added.

Images from across the region showed waterlogged homes and cars submerged in muddy floodwaters, while some people took to paddling in small rubber lifeboats or tyre inner-tubes to get around.

The disaster marked Jakarta's worst flooding since 2013 when several dozen people were killed when the city was inundated by monsoon rains.

Jakarta is regularly hit by floods during Indonesia's rainy season, which started in late November.

On Wednesday, service at Halim Perdanakusuma airport, which handles commercial and military planes, was temporarily shut due to severe flooding on its runways, according to the transport ministry.

Many flights were transferred to Jakarta's main Soekarno-Hatta International Airport.
