HANOI - HIGH waves destroyed at least 27 seaside houses in a southern Vietnamese resort at the weekend and were threatening over 100 more, emergency service officials said on Monday.

There were no immediate reports of any casualties from Phan Thiet town, about 200km east of the southern business hub of Ho Chi Minh City.

The buildings were destroyed when high waves pounded the shoreline, causing tens of thousands of dollars in property damage, said the provincial flood and storm control committee in a report sent to AFP.

Hundreds of soldiers, border guards and youth volunteers had been mobilised to stabilise more than 100 other buildings that were also threatened with collapse, said the report.

In Ho Chi Minh City, meanwhile, high waves on Sunday broke part of a sea dyke, flooding more than 200 households, the state-controlled Tuoi Tre daily said. -- AFP
