United Nations investigators say they have recorded "systematic" torture in Myanmar's military-run detention facilities, including beatings, electric shocks and gang rape.
Myanmar has been consumed by civil war since the military deposed the civilian government in a 2021 coup, with troops fighting an array of pro-democracy guerrillas and ethnic armed groups.
The fighting has been accompanied by a crackdown in which nearly 30,000 people have been arrested, according to the Assistance Association for Political Prisoners monitor group.
A report by the UN's Independent Investigative Mechanism for Myanmar (IIMM) said it had identified "serious abuses during interrogations and in detention facilities".
"We have uncovered significant evidence, including eyewitness testimony, showing systematic torture in Myanmar detention facilities," Nicholas Koumjian, head of the IIMM, said in a statement accompanying the 16-page annual report, which was released on Tuesday.
A junta spokesman could not be reached for comment on the allegations laid out in the report, which drew on testimony from nearly 600 eyewitnesses.

It said there had been "systematic commission" of torture, including "sexual slavery", the "burning of sexual body parts with cigarettes or burned objects", and fingernails being pulled out with pliers.
It also found evidence "indicating that children — ranging from two to 17 years of age — have been detained, often as proxies for their parents".
"Some of the detained children have been subjected to torture, ill-treatment or sexual and gender-based crimes," it added.
The torture sometimes resulted in death, the report said.

"We are working towards the day when the perpetrators will have to answer for their actions in a court of law."
The International Criminal Court's chief prosecutor has already requested an arrest warrant for junta chief Min Aung Hlaing, who ousted and jailed elected leader Aung San Suu Kyi.
That warrant request relates to alleged atrocities committed by the military on Myanmar's Rohingya minority in 2017.
All sides in Myanmar's civil war have been accused of committing war crimes, and the IIMM report said it had also identified cases where opposition groups had committed summary executions of captives.
