Thailand authorities are battling to protect the capital, Bangkok, from the flood waters that devastated central provinces, while officials in neighboring Burma said Sunday floods there killed at least 100 people.

Bangkok Governor Sukhumbhand Paribatra said the city's flood defenses are prepared, but face a new wave of waters now bearing down from the northern provinces of Pathumthani and Ayutthaya.

The floods are part of a major inundation across Southeast Asia that have claimed more than 700 lives and forced millions from their homes.

Thailand's death toll has reached 356, including some 50 children. More than 110,000 people are displaced, and the economic damage continues to mount. Economists estimate the cost of the floods at $6 billion. In Cambodia, close to 250 people were killed so far, while at least 100 people died in Burma and more than 55 in Vietnam.

A growing number of countries are pledging aid to the flood-ravaged region.
