Railway stations and major roads were underwater in the South Korean capital Seoul after record-breaking rains caused severe flooding, with at least eight people dead and seven more missing, officials said.
Dramatic images shared on social media showed people wading through waist-deep water, metro stations overflowing, and cars half-submerged in Seoul's wealthy Gangnam district after torrential rain battered the city.
The downpour that began yesterday is the heaviest rainfall in South Korea in 80 years, according to Seoul's Yonhap news agency.
Local reports said three people living in a banjiha - cramped basement flats of the kind made famous in Bong Joon-ho's Oscar-winning "Parasite" - including a teenager, died as their apartment was inundated by floodwaters.
Parts of Seoul, surrounding Gyeonggi province and port city Incheon recorded rains of more than 100mm per hour last night, according to the Yonhap news agency.
The per-hour precipitation in the capital's Dongjak district surpassed 141.5mm at one point, the heaviest downpour since 1942.
President Yoon Suk-yeol ordered government officials to evacuate residents from high-risk areas and encouraged businesses to allow employees flexible commuting hours this morning.
"Nothing is more precious than life and safety. The government will thoroughly manage the heavy rain situation," he wrote on his Facebook account.
Neighbourhoods close to the presidential residence in southern Seoul were affected, according to images of the flooding posted on social media.
Power outages were reported across the capital area, while some operations of the Seoul metro as well as railway services were temporarily disrupted by the heavy rain.
The Seoul express bus terminal in Gangnam was submerged, and flood water also leaked into a cafe and library at the COEX Convention and Exhibition Center in the same area.
An image of a man in a suit sitting on the bonnet of a submerged vehicle in the wealthy district in southern Seoul, which was featured in Psy's 2012 K-pop hit "Gangnam Style", went viral online.
