YouTube removed five channels run by Myanmar’s military for violating its guidelines, it announced Friday, as demonstrators defied growing violence by security forces and staged more anti-coup protests ahead of a special U.N. Security Council meeting on the country’s political crisis.

YouTube said it is watching for any further content that might violate its rules. It earlier pulled dozens of channels as part of an investigation into content uploaded in a coordinated influence campaign, according to Associated Press.

The decision by YouTube followed Facebook’s earlier announcement that it has removed all Myanmar military-linked pages from its site and from Instagram, which it also owns.

The escalation of violence by security forces has put pressure on the world community to act to restrain the junta, which seized power on February 1, 2021 by ousting the elected government of Aung San Suu Kyi.

Large protests against military rule have occurred daily in many cities and towns. Security forces escalated their crackdown this week with greater use of lethal force and mass arrests. At least 18 protesters were shot dead on Sunday and 38 on Wednesday, according to the U.N. Human Rights Office. More than 1,000 people have been arrested, the independent Assistance Association for Political Prisoners said.

Many cases of targeted brutality have been captured in photos and videos that have circulated widely on social media. Videos have showed security forces shooting people at point-blank range and chasing down and savagely beating demonstrators.
