Interior Ministry: Flooding has killed 442 people

It is Thailand's worst flooding in decades

Bangkok, Thailand CNN  — 

Thailand’s floodwaters inched toward downtown Bangkok Saturday, threatening some subway stations as leaders urged residents not to open defenses set up to divert the waters from the capital.

At least six subway stations are on the floodway, authorities said.

Residents have threatened to open the defenses to drain water from their flooded neighborhoods, the Bangkok Metropolitan Administration said.

“The main problem of solving flood is no longer technical but people,” Prime Minister Yingluck Shinawatra said during the weekly radio address.

The flooding has claimed 442 lives, the Interior Ministry said. Of Thailand’s 64 provinces, 25 have been affected.

Bangkok’s central business district is still dry but other parts of the bustling metropolis of 12 million people are inundated.

The flooding has had an enormous business impact as many factories and offices have been under water for more than a month. That includes Hi Tech Industrial Park, where Canon and Sony own assembly plants.
