The death toll from a powerful earthquake that struck Indonesia's Central Sulawesi province has risen to three, while dozens of others were injured and thousands affected, authorities said.

Indonesia's National Disaster Management Agency (BNPB) reported that three people were killed and 17 others seriously injured after the magnitude 6.7 earthquake hit the province on Tuesday.

The agency said 91 people sustained minor injuries, while a total of 6,412 residents were affected by the disaster. Sigi district was identified as the hardest-hit area, with damage reported in a number of villages.

The tectonic earthquake struck at 11:27 a.m. local time on Tuesday. According to authorities, the epicenter was located on land about 42 kilometers southeast of Palu at a depth of 10 kilometers.

No tsunami warning was issued, and officials confirmed that the earthquake did not trigger a tsunami.

Emergency response efforts remain underway as authorities continue damage assessments and provide assistance to affected communities.

The government has distributed emergency supplies, including tents, food packages, mattresses and blankets, while rescue and relief teams continue operations in the affected areas.

Indonesia is located along the Pacific "Ring of Fire," a seismically active zone where earthquakes and volcanic eruptions occur frequently. (ILKHA)
