Sri Lanka has so far confirmed that five people died and 33 remain missing in last week's mudslide at a central tea plantation as authorities continue to struggle to determine how many people were buried.

The Disaster Management Center noted in its report Sunday that the figures could change as rescue workers continue to search for bodies in the debris at the Koslanda plantation in Badulla district, about 140 miles (220 kilometers) east of Colombo.

Soon after Wednesday's disaster, the center said at least 250 people were missing but it has gradually reduced the number based on police records.

Sri Lanka, formerly called Ceylon, is one of the world's leading tea producers.
