The death toll from the devastating quake and tsunami on Indonesia's Sulawesi island neared 2,000 on Monday, but thousands more are believed unaccounted for and officials said search teams plan to stop looking for victims later this week.

More than 5,000 people could still be missing in Indonesia, following a powerful quake that hit the island of Sulawesi last week, officials said on Sunday.
"Most of the bodies we have found are not intact, and that poses a danger for the rescuers". The number of bodies lying beneath the mound of rubble, metal and mud is unknown.

The figure drastically increases the estimates for those who disappeared when the disaster struck 10 days ago.
