A 6.7-magnitude earthquake struck off Indonesia's Sumbawa island on Monday, killing three, injuring 45 and damaging hundreds of homes, officials said as aftershocks rattled nerves.
Some buildings collapsed in Dompu and Bima districts as officials rushed to reach remoter areas and frightened residents clustered outdoors.
Health ministry spokesman Rustam Pakaya told AFP that three people had died, including a five-year-old boy, while 45 people had been injured. He did not provide any further details on the fatalities.
Most of the injured were being treated at the general hospital in Dompu, one of the worst-affected districts, said a doctor there, Suriyani.
"We received 34 people injured. Some with slight injuries have gone home already but some 20 people are still under hospital treatment, with broken bones, open wounds and head injuries caused by collapsing walls," she told AFP.
Siti Hajar, Bima health ministry chief, told AFP that one person had been hospitalised and 10 others had slight injuries.
She said 20 houses had been destroyed and hundreds more damaged.
Suhartomo, her counterpart in Dompu, said that 10 houses had collapsed in Dompu town and about 90 per cent had suffered cracks. Officials were headed to the worst hit area of Kilo to check conditions there, he added.
The Indonesian meteorological agency measured the quake at 6.7, though the US Geological Survey (USGS) later revised its same initial calculation down to 6.
