Dozens of people are feared missing after a landslide early on Wednesday at a jade mine in northern Myanmar.
The landslide in the Hpakant area of Kachin State happened at around 4:00 am (2130 GMT on Tuesday) and there were fears that about 80 people had been swept into a lake by mining waste, an official at the Kachin Network Development Foundation said.
"Authorities arrived at the site around 7 am and are conducting the search," Dashi Naw Lawn, an official at the civil society group said by telephone, adding that no dead bodies had been found up to now.
The Mizzima news portal and Khit Thit media also reported dozens appeared to be missing in the incident in Hpakant, which is the centre of Myanmar's secretive jade industry.
In another landslide last weekend, media reported at least six people died.
Deadly landslides and other accidents are common in the poorly regulated mines of Hpakant, which draw impoverished workers from across Myanmar in search of gems mostly for export to China.
Economic pressures due to the COVID-19 pandemic have drawn more migrants to the jade mines even as conflict has flared since Myanmar's military seized power in a coup in February.
The ousted government of Nobel laureate Aung San Suu Kyi had pledged to clean up the industry when it took power in 2016, but activists say little has changed.
In July last year, more than 170 people, many of them migrants, died in one of the worst disasters in Hpakant after mining waste collapsed into a lake.
Myanmar produces 90 per cent of the world's jade and most of it comes from Hpakant.
