Myanmar's UN envoy removed for denouncing military crackdown

Military leaders say Kyaw Moe Tun 'betrayed' the country after his impassioned speech

Myanmar's ambassador to the United Nations Kyaw Moe Tun holds up three fingers at the end of his speech to the UN.

Myanmar's junta dismissed its United Nations ambassador on Saturday for breaking ranks to denounce a military crackdown on protesters across the country.

The country has been shaken by a wave of demonstrations since the armed forces toppled civilian leader Aung San Suu Kyi on February 1.

Authorities have ramped up the use of force to suppress dissent, deploying tear gas, water cannon and rubber bullets to disperse some protests. Live rounds have been used in isolated cases.

In justifying its seizure of power, the military has alleged widespread fraud in the November elections, which Suu Kyi's party won in a landslide, and promised fresh polls in a year.

But its ambassador to the United Nations on Friday broke ranks and made an emotional appeal to the international community for "the strongest possible action... to restore democracy".

Kyaw Moe Tun also pleaded with his "brothers and sisters" in Burmese to keep fighting.

"This revolution must win," he said, flashing the three-finger salute that has become a symbol of resistance against the junta.

By Saturday night, state-run TV announced that Kyaw Moe Tun was no longer Myanmar's UN ambassador.

"(He) didn't follow the order and direction by the state and betrayed the country," according to a MRTV broadcast.

"That is why he is revoked from his position starting from today."

News of Kyaw Moe Tun's removal follows a day of crackdowns and mass arrests by Myanmar's security forces as the country enters its fourth week of daily protests against the generals' grip on power.

Chaos unfolded across commercial hub Yangon, with police closing in early on peaceful demonstrators and deploying rubber bullets to disperse them from Myaynigone junction.

Protesters scattered into residential streets and started building makeshift barricades out of stacked tables and trash cans to stop the police.

Many wore hard hats and gas masks, wielding homemade shields for protection.

"What are the police doing? They are protecting a crazy dictator," the protesters chanted angrily.

Local reporters broadcast the chaotic scenes live on Facebook, including the moments when the shots rang out, which AFP reporters on the ground also witnessed.

"We want to fight until we win," said protester Moe Moe, 23, who used a pseudonym.

At nearby Hledan junction several rounds of stun grenades were fired, according to AFP reporters.

Another protest near a shopping centre in nearby Tamwe Township was broken up by police.

Aye Myint Kyi, a distraught mother of one shopper, said she reached her daughter briefly on the phone, who said she was being taken.

"I don't know where she was taken," she told AFP, crying. "She was unjustly arrested."

In the central city of Monywa, a rally had barely started before police and soldiers moved in on demonstrators, said a medic with a local emergency rescue team.

Htwe Aung Zin said his team had been "sent a man who was severely injured in his leg from the police crackdown", adding that they treated 10 others with minor injuries.

He declined to say what kind of bullets caused the man's injury.

Another medic -- who did not give their name -- told AFP that a woman with severe injuries had been sent to the intensive care unit.

Meanwhile, two local media outlets saw their journalists arrested as they attempted to broadcast live video of protests on Facebook.
