In addition to the fatalities, the weekend quakes injured hundreds of people, damaged more than 800 houses and forced about 14,000 people out of their homes, the United Nations said in a statement from its New York headquarters.

The Indonesian National Meteorological Geophysical and Climatology Agency said the first temblor hit at 4:43 a.m. local time and measured 7.2 on the Richter scale. A second earthquake measuring 7.6 hit at 7:33 a.m. local time, followed by more than a dozen aftershocks.

The Indonesian government has transported relief supplies to the affected areas, the statement said.
