Aid donors mobilize to help flood-stricken Myanmar, where floodwaters are moving downriver

Flood victims gather inside a monastery, opened as a temporary relief camp, in Myauk U, Rakhine State, western Myanmar, Tuesday, Aug 4, 2015. New devastation is feared in Myanmar as water from the badly flooded central and northern regions flows down rivers to the country's more populous areas. Officials say the death toll from weeks of almost continuous rain is 46, with more than 200,000 people affected by flooding in 11 of the country's 14 states and divisions.

Other nations and relief organizations are moving to help Myanmar cope with floods that have caused 69 deaths and affected another 260,000 people after more than a month of heavy monsoon rains and a cyclone.

The director of the Ministry of Social Welfare, Relief and Resettlement, Phyu Lei Lei Tun, warned Wednesday that the Irrawaddy Delta, the country's rice bowl, was at critical risk of calamitous flooding as water surged down rivers from badly inundated areas further north.

At a regional meeting in Malaysia, U.S. Secretary of State John Kerry said Washington would soon announce a flood relief package. The Chinese Embassy announced on its website that a 10-member Chinese rescue team arrived in Yangon on Tuesday.
