A monintoring group called for international action after Myanmar's military junta aired images of anti-coup protesters that appeared to show them having been tortured and bruised.
The images were tweeted by The Asistancce Association for Political Prisoners (AAPP), a human rights organisation working to secure the release of prisoners in the country.
"Emboldened through impunity. This junta uses torture as its policy. AAPP is concerned for all those detained particularly in undisclosed locations If international community does not act. Torture, and to death, will clearly continue," AAPP said in a tweet.
According to AAPP, as of Sunday, 3,229 protesters have beendetained or sentenced, and930 have been issued arrest warrants. The monitoring group said737 people have been killed since the coup ousted the government led by Aung San Suu Kyi in February.
Images carried on Sunday byjunta-owned MRTV showed six detainees, including two women. Their faces appearedengorged, bloodied or bruised.The jaw of one of the women was swollen and she appeared to have a black eye.
The MRTV report said the protesters werearrested on Sunday in Yankin, a suburb of Yangon, the country's biggest city.
Kim Jolliffe, a researcher on Myanmar, said in a tweet: "The Myanmarjunta's strategy from start to finish is based on the same gambit: "We can be more brutal than you... We can be more shockingly hurtful and terrifying than you" That is all they have. But it knows no bounds."
