At least 35 people were killed after a 6.2-magnitude earthquake struck Indonesia's Sulawesi island on Friday. The country's meteorological agency warned of more aftershocks, possibly strong enough to trigger a tsunami.
The huge tremor struck 6 km (3.73 miles) northeast of the town of Majene, at the shallow depth of 10 km, just before 1.30 a.m. The quake sent thousands of frightened residents out of their homes and fleeing for higher ground.
The earthquake and aftershocks caused three landslides, cut electricity, damaged bridges to regional hubs such as the city of Makassar, and damaged more than 60 homes, two hotels and the provincial governor's office, where at least two people were buried under rubble, Reuters reported, citing authorities.

"Praise be to God, for now OK, but we just felt another aftershock," said 26-year-old resident Sukri Efendy.
Darno Majid, chief of the disaster agency in West Sulawesi, told Reuters that 35 people had been killed in Majene, and in the neighbouring district of Mamuju, with more deaths likely to be confirmed as rescue workers fanned out.
Initial information from the national disaster mitigation agency showed that 637 people had been injured in Majene, and two dozen in Mamuju.
No tsunami warning was issued but the head of Indonesia's Meteorology and Geophysics Agency (BMKG), Dwikorita Karnawati, told a news conference that aftershocks could follow, with a possibility that another powerful quake could trigger a tsunami.
There had been at least 26 aftershocks, she said, with Friday's quake preceded by a 5.9 magnitude quake on Thursday afternoon.
West Sulawesi provincial government spokesman Safaruddin said authorities needed to restore telecommunications, mend several damaged bridges and deliver tents, food and medical supplies.
Pictures of the aftermath appeared on social media as the head of the disaster agency and social affairs minister were scheduled to fly in.
Videos showed residents fleeing to higher ground on motorcycles, and a child trapped under the rubble as people tried to remove debris with their hands.
