Naypyitaw, Myanmar - Myanmar leader Aung San Suu Kyi on Tuesday condemned human rights violations in Rakhine state and said violators would be punished, but she did not address UN accusations of a campaign of ethnic cleansing by the military, drawing a cool international response.

She made the remarks in her first address to the nation since attacks by Rohingya Muslim insurgents on August 25 led to a military response that has forced 421 000 Rohingya Muslims, more than half of them children, into neighbouring Bangladesh.

Western diplomats and aid officials, hoping for an unequivocal condemnation of violence and hate speech, welcomed the tone of the Nobel Peace laureate's message, but some doubted if she had done enough to deflect global criticism.

At the annual United Nations General Assembly, U.N. Secretary-General Antonio Guterres repeated a call for an end to military operations and restoration of humanitarian access.

"I take note of State Councilor Aung San Suu Kyi's address today and their intention to implement the recommendations of the advisory committee for Rakhine state, that was chaired by Kofi Annan, within the shortest time possible," he said.

"But let me emphasize again, the authorities in Myanmar must end the military operations, allow unhindered humanitarian access and recognize the right of refugees to return in safety and dignity; and they must also address the grievances of the Rohingya, whose status has been left unresolved for far too long."

Britain said on Tuesday it had suspended its military training programme in Myanmar because of the violence in Rakhine state. French President Emmanuel Macron termed what had occurred "ethnic cleaning" and told the U.N. General Assembly that France would start a Security Council initiative in response, but gave no details.

A European Union spokeswoman said immediate priorities were a cessation of violence and full access to all humanitarian aid workers.

She said Suu Kyi's invitation to the diplomatic corps to visit Rakhine was "a step forward," but added: "Myanmar's leadership needs to show that the democracy they fought so hard for can work for all the people of Myanmar, beyond ethnic, social and religious boundaries."

Nigerian President Muhammadu Buhari, in his speech to the General Assembly, likened the violence in Myanmar to genocides in Bosnia and Rwanda and urged a halt to the "ongoing ethnic cleansing" and the safe return of refugees.

Amnesty International described Suu Kyi's speech as "little more than a mix of untruths and victim-blaming", saying she and her government were "burying their heads in the sand" for ignoring the army's role in the violence.

"We condemn all human rights violations and unlawful violence. We are committed to the restoration of peace and stability and rule of law throughout the state," Suu Kyi said in her address in the capital, Naypyitaw.

"Action will be taken against all people, regardless of their religion, race and political position, who go against the law of the land and violate human rights," she said.

Long feted in the West as a champion of democracy in the Buddhist-majority country during years of military rule and house arrest, Suu Kyi has faced growing criticism for saying little about abuses faced by the Rohingya.

The United States urged Myanmar on Monday to end military operations, grant humanitarian access, and commit to aiding the safe return of civilians to their homes.

Myanmar's generals remain in full charge of security and Suu Kyi did not comment on the military or its actions, except to say there had been "no armed clashes and there have been no clearance operations" since Sept. 5.

Rohingya refugees arriving in Bangladesh have told of soldiers and Buddhist civilians attacking and burning villages as recently as last Friday. It was not possible to verify their accounts.

BURNING VILLAGES

Rights monitors and fleeing Rohingya say the army and Rakhine Buddhist vigilantes have mounted a campaign of arson aimed at driving out the Muslim population. The U.N. rights agency said it was "a textbook example of ethnic cleansing".

Myanmar rejects the charge, saying its forces are tackling insurgents of the Arakan Rohingya Salvation Army (ARSA), which the government has declared a terrorist group and accused of setting the fires and attacking civilians.

Western governments that backed Suu Kyi's campaign against military rule still see her as the best hope for Myanmar's political and economic transition.

But she has to avoid angering the powerful army.

She also has to avoid alienating supporters by being seen to take the side of a Muslim minority that enjoys little sympathy in a country that has seen a surge of Buddhist nationalism.

Some diplomats said she had not squarely addressed the problem of violence in her speech.

But her domestic audience was happy.

Thousands of supporters cheered and let balloons float into the sky in the main city of Yangon as they watched her speech on a big screen. Social media saw a blizzard of posts with the message: "We stand with Aung San Suu Kyi".

Phil Robertson of Human Rights Watch said satellite images showed about half of all Rohingya villages had been torched and it was time that Suu Kyi, the government and military faced the fact that the security forces "shoot and kill who they want."

Amnesty International said there was "overwhelming evidence" the security forces were engaged in ethnic cleansing.

'READY TO EXPLODE'

In Geneva, the head of a U.N. investigation into the violence said his team had heard testimony that suggested Myanmar's security forces may be committing rights violations.

"What they have come up with reflects in general the reporting of the international media," Marzuki Darusman said, referring to a small team of investigators talking to refugees in Bangladesh.

Myanmar has declined to issue visas to Darusman's team, but he said he was more hopeful following Suu Kyi's speech in which she spoke of allowing diplomats access to Rakhine state.

Suu Kyi, 72, said her government had been promoting harmony between the Muslim and largely Buddhist ethnic Rakhine communities. But a government official there did not share her optimism.

"They have no trust for each other," the state's secretary, Tin Maung Swe, told Reuters, adding that tensions were high.

"The situation is ready to explode."

Suu Kyi said she was committed to recommendations made by the advisory team led by Annan, a former U.N. secretary-general, which last month suggested a review of a law that links citizenship and ethnicity and leaves most Rohingya stateless.

On the return of refugees, Suu Kyi said Myanmar was ready to start a verification process and "refugees from this country will be accepted without any problem".
