Typhoon Damrey, now a tropical storm, pounded northern and eastern Vietnam Tuesday, killing at least one person, injuring several others and causing widespread damage.

Vietnamese authorities say Damrey came ashore early this morning in Thanh Hoa province, south of Hanoi, with heavy rain and winds around 100 kilometers per hour.

Officials say some protective dikes along the eastern coastline were seriously damaged, and several provinces lost electricity.

Hanoi Radio said the storm weakened as it moved towards Laos.

Before hitting Vietnam, Damrey slammed into the southern Chinese provinces of Hainan and Guangdong on Monday. China' state news agency, Xinhua, said the storm killed at least 16 people on Hainan and caused an island-wide blackout.

Chinese officials said Damrey caused more than $1 billion in direct losses, mainly to agriculture.
