"He said it's worth dying for," she said. "He is worried about people not joining the protest. If so, democracy will not return to the country."

More than 2,000 people have been arbitrarily detained since the coup, according to AAPP, many of them kept out of contact from family and friends, their condition or whereabouts unknown.

CNN cannot independently verify the arrest numbers or death toll from AAPP.

Myanmar's state run daily newspaper published a notice on Wednesday reinforcing the military's narrative that it is using minimum force against protesters.

On Thursday, the UN special rapporteur for human rights in Myanmar, Tom Andrews, said in a statement to the UN Human Rights Council in Geneva that a "growing body of reporting" indicates the junta's security forces are committing "acts of murder, imprisonment, persecution and other crimes as part of a coordinated campaign, directed against a civilian population, in a widespread and systematic manner, with the knowledge of the junta's leadership."

The "brutal response," he said, is "thereby likely meeting the legal threshold for crimes against humanity."

He called on UN member states to stop the flow of revenue and weapons to the junta, saying multilateral sanctions "should be imposed" on senior leaders, military-owned and controlled enterprises and the state energy firm, Myanmar Oil and Gas Enterprise.

His statement came after rights group Amnesty International released a report saying the military were embarking on a "killing spree" in Myanmar, using increasingly lethal tactics and weapons normally seen on the battlefield against peaceful protesters and bystanders.

By verifying more than 50 videos from the ongoing crackdown, Amnesty's Crisis Evidence Lab confirmed security forces appear to be implementing planned, systematic strategies, including the ramped-up use of lethal force, indiscriminate spraying of live ammunition in urban areas, and that many of the killings documented amount to extrajudicial executions.

"These Myanmar military tactics are far from new, but their killing sprees have never before been livestreamed for the world to see," said Joanne Mariner, director of crisis response at Amnesty International. "These are not the actions of overwhelmed, individual officers making poor decisions. These are unrepentant commanders already implicated in crimes against humanity, deploying their troops and murderous methods in the open.

Fleeing to India

There is evidence the violence is forcing people to flee the country. Between 200 and 300 people have crossed the border from Myanmar into India's northeastern state of Mizoram, fleeing the unrest, Mizoram's chief minister told CNN.

That number includes police, civil servants, their family members, and other civilian and the number of people fleeing increases daily, according Chief Minister PU Zoramthanga.

"We (the Mizoram government) are not sending them back as a humanitarian point of view. When somebody enters the land, the country's border, for fear of their lives we cannot simply send them back. They are not criminals. It is a political issue," he said.

Zormanthanga added that people are given food and shelter, and many have family in Mizoram. He said it is up to the Indian central government on how to deal with people crossing the border.

Suu Kyi accused of bribery

Military spokesperson Brig. Gen. Zaw Min Tun said in a news conference that Suu Kyi accepted illegal payments worth $600,000, as well as gold, while in government, according to Reuters.

The spokesperson added that the information had been verified following a complaint from a former Yangon regional minister, and an anti-corruption committee was investigating.

Suu Kyi's lawyer, Khin Maung Zaw told CNN "the allegations are a complete fabrication."

"I have been in politics in Myanmar for nearly 40 years, and in all these years I have not witnessed such shameless allegations" he said. "We are in a country where the people have seen lots of corruption in the past and many misbehaviors, but Aung San Suu Kyi is not in that sphere of corruption."

He added that while he has had "many disagreements" with Suu Kyi, "when it comes corruption, bribery, greed -- this is not her, she is not that kind of woman."

Along with Suu Kyi, ousted President Win Myint, his wife, and several cabinet ministers were being investigated for allegedly asking for and accepting "money from some entrepreneurs," the spokesperson said, without clarifying, according to Reuters.

Suu Kyi and Win Myint remain under house arrest.

The military, headed by coup-leader Gen. Min Aung Hlaing, took full control of the country last month, ousting Suu Kyi's democratically elected government, which had won a landslide in November 2020 elections.

The army justified its action by alleging widespread voter fraud in that poll -- only the second democratic vote since the previous military junta began a series of reforms in 2011.

In a video statement played to the UN Human Rights Council, Myanmar's permanent secretary of the Ministry of Foreign Affairs Chan Aye said: "In recent days, authorities concerned have been paying attention to maintaining law and order in the country," and "authorities have been exercising utmost restraint to deal with the violent protests."

Chan Aye also said the military leadership remains committed to "free and fair multiparty democratic elections."

In a statement, China's ambassador to the UN, Zhang Jun, said "it is important the Council members speak in one voice. We hope the message of the Council would be conducive to easing the situation in Myanmar."

Kyaw Moe Tun said the message "does not meet the peoples' expectation," saying up against the brutality of the military "we all feel helpless" and called on the international community for protection.
