An undersea earthquake off Indonesia’s northern Aceh province has killed at least 52 people, the BBC reports.
The magnitude 6.5 quake struck just off the north-east coast of Sumatra island, where dozens of buildings have collapsed and many people are feared trapped under rubble.
Indonesia’s meteorological agency said there was no risk of a tsunami.
In 2004, Aceh was devastated by a tsunami that killed more than 160,000 people in Indonesia alone.
The US Geological Survey said the earthquake struck just offshore at 05:03 local time (22:03 GMT Tuesday) at a depth of 17.2km.
At least 70 people have been seriously injured, officials said, and hundreds of minor injuries have been reported.
A spokesman for the national disaster agency said more than 200 shops and homes had been destroyed, along with 14 mosques. A hospital and school were also badly damaged.
