JAKARTA, July 24 (Xinhua) -- Twenty people were killed and 52 others still could not be found after a landslide and flood in Central Sulawesi province, in eastern part of Indonesia on Sunday evening, the Disaster Management Agency said here Tuesday.

    The natural disaster in Batu Bare and Tomboyali districts in Marowali regency had destructed over one hundred houses and infrastructure, including transport facilities, said officials.

    "Twenty bodies have been found and the other 52 still go missing," an official of the agency Giri Trigondo told Xinhua here.

    The official said that rescue for the missing people was still underway.

    Separately, from the site of the disaster, the head of the Crisis Management Center of the Health Ministry Rustam Pakaya saidthat poor weather and transport facilities had hampered delivering of aids from outside the island.

    "The weather is poor and many bridges are broken off," he told Xinhua on telephone from the regency.

    Pakaya said that rains which was blamed for the cause of the disaster still poured down on the regency on Tuesday.

    He said that waters still submerged houses in several villages.

    "More than two-meter-high water inundated 16 villages. And 20,201 people were on the brink of danger," he said.

    The waters had hampered the shifting of aids to the thousands of residents, said Pakaya.

    "The access to the villages is cut off. The medical team visits the residents by bamboo raft," he said.

    The official of the disaster management agency Trigono said that over nine thousands people had fled homes and lived in schools buildings and tents.

    Indonesia has been frequently hit by flood and landslide due to lack of forest covered-areas, which could not hold excessive waters during heavy rain.

    Forest destruction and illegal logging have caused the lack covered areas.
