HANOI, Jan. 12 (Xinhua) -- At least 69 houses have collapsed into the sea due to broken dyke and more than 100 are under threat of collapse as more strong waves and high tides are forecast to hit the southern Binh Thuan province of Vietnam in the coming days, the local newspaper Labor reported Monday.

    The three-meter dyke was so weak that the high tide broke it, said the newspaper.

    No casualty has been reported. Hundreds of local residents are in difficulty as they are facing the risk of becoming homeless. Losses were estimated at millions of U.S. dollars, said the newspaper.

    Local authorities and residents have been struggling to reinforce the broken dyke by piling up sandbags against the emergency dike system to prevent further damage, said the newspaper.

    The Southern Hydro meteorological Center warned of more tides in the province in the next few days. Tides are forecast to exceed level three, the very dangerous grade used by Vietnam Central Committee for Flood Control and Prevention, said the newspaper.

    The southern region of Vietnam has also experienced the abnormal coldest weather for the past nine years with the temperature hovering from 16 to 17 degrees Celsius. The region is expected to witness two other cold spells before the country's traditional Lunar New Year holiday, said the center.
