A young woman protester in Myanmar died on Friday after being shot in the head last week as police dispersed a crowd, her brother said, the first death among opponents of the Feb. 1 military coup since demonstrations began two weeks ago.

News of the death came as baton-wielding police and soldiers broke up a procession of people carrying banners of ousted leader Aung San Suu Kyi in the northern town of Myitkyina and thousands returned to the streets of the main city of Yangon.

Mya Thwate Thwate Khaing, who had just turned 20, had been on life support since being taken to hospital on Feb. 9, after she was hit by what doctors said was a live bullet at a protest in the capital, Naypyitaw.

"I feel really sad and have nothing to say," said her brother, Ye Htut Aung, speaking by telephone.

Protesters set up a shrine for her on a pavement in Yangon, with pictures, flowers and the flag of Suu Kyi's party.

"I'm proud of her and I'll come out until we achieve our goal for her," Nay Lin Htet, 24, told Reuters.

Friday marked two weeks of daily demonstrations against the military's seizure of power and its detention of veteran democracy campaigner Suu Kyi.

The protests throughout the ethnically diverse country have been more peaceful than the bloodily suppressed demonstrations during nearly 50 years of direct military rule up to 2011.

But police have fired rubber bullets several times to break up crowds, as well as water cannon and catapults. The army says one policeman has died of injuries sustained in a protest.

The UN office in Myanmar and international rights groups called on the security forces to avoid using force.

In Myitkyina, police and soldiers sent protesters scattering down a street lined with shops, video on social media showed.

Rights activist Stella Naw said about 50 people were detained but later released.

There have been clashes in Myitkyina, capital of Kachin State, over the past two weeks with police firing rubber bullets and using catapults to disperse crowds.

Police in Yangon sealed off the city's main protest site near the Sule Pagoda, setting up barricades on access roads to an intersection where tens of thousands have gathered this week.

Hundreds of people gathered at the barricades anyway and several thousand formed a procession at another site.

The demonstrations have at times taken on a festive air and LGBT rights campaigners marched in Yangon while in the second city of Mandalay, chefs set up melons carved with the message "Justice for Myanmar".

'SYMBOLIC' SANCTIONS

As well as the protests, a civil disobedience campaign has paralysed much government business and international pressure is building on the military.

Britain and Canada announced new sanctions on Thursday and Japan said it had agreed with India, the United States and Australia on the need for democracy to be restored quickly.

The junta has not reacted to the new sanctions. On Tuesday, an army spokesman told a news conference that sanctions had been expected.

There is little history of Myanmar's generals giving in to foreign pressure and they have closer ties to neighbouring China and to Russia, which have taken a softer approach than long critical Western countries.

Junta leader Min Aung Hlaing was already under sanctions from Western countries following the 2017 crackdown on the Muslim Rohingya minority.

"Sanctioning military leaders is largely symbolic, but the moves to sanction military companies will be much more effective," said Mark Farmaner, director of the Burma Campaign UK group.

Britain froze assets and imposed travel bans on three generals and took steps to stop aid helping the military and to prevent British businesses working with the army. Canada said it would take action against nine military officials.

After decades of military rule, businesses linked to the army have a significant stake across the economy, with interests ranging from banking to beer, telecoms and transport.

The army seized back power after alleging fraud in Nov. 8 elections won by Suu Kyi's National League for Democracy, detaining her and other top party members and halting a transition to democracy that had begun in 2011. The electoral commission had dismissed the allegations of fraud.

Myanmar's Assistance Association for Political Prisoners said 521 people had been detained, with 44 released, as of Thursday.

Suu Kyi, 75, faces a charge of violating a Natural Disaster Management Law as well as charges of illegally importing six walkie talkie radios. Her next court appearance has been set for March 1.
