Colombo  - At least four people drowned and some 136,000 have been displaced in floods sweeping areas of Sri Lanka over the past five days, the Disaster Management Centre (DMC) said Sunday.

Keerthi Ekanayaka, Coordinating Officer of the DMC in the north- west, west and south, said more than 25,000 homes were affected.

The heavy rains also affected Tamil rebel-held northern areas, where government troops are continuing military operations.

At least 150,000 civilians had already been displaced by the fighting in the north, most living in temporary shelters. (dpa)
