Hundreds are dead and missing in South East Asia, where some of the heaviest rain in decades has swept the region, BBC reported.

Monsoon rain exacerbated by tropical storms has caused some of the worst flooding in years, with millions affected in Indonesia, Malaysia and Thailand.

The death toll on Indonesia's Sumatra island has passed 300 and there are fears it could increase further with dozens still missing.

Evacuation efforts are still under way there, with major roads cut off and internet and electricity only partially restored, according to BBC.
