Another anti-coup protester was shot dead in Myanmar on Friday as a UN envoy urged a divided Security Council to hear the nation's "desperate pleas" and take swift action to restore democracy.

Despite an increasingly brutal crackdown by the military authorities that has seen more than 50 people killed, protesters took to the streets again in towns around the country to denounce the February 1 coup.

In Mandalay, Myanmar's second-largest city, hundreds of engineers took to the streets crying "Free our leader" in reference to ousted State Counsellor Aung San Suu Kyi, detained by the military since the first night of the takeover.

A 26-year-old man helping at barriers set up in the city to slow security forces died after being shot in the neck, medical officials told AFP.

The killing follows the deadliest day of the crackdown so far on Wednesday, when the United Nations said at least 38 people were killed as graphic images showed security forces firing into crowds and bloodied bodies dragged away.

Police also fired tear gas at demonstrators in the southern city of Dawei while protesters in the commercial capital Yangon were defiant despite the danger.

"Scared, yeah, I'm very scared to stay on the frontline. But we believe in our comrades and we promise to protect each other if someone is injured," protester Didi, 27, told AFP.

The generals have shown no sign of heeding calls for restraint despite mounting international pressure, including targeted sanctions by Western powers.

The Security Council took up the escalating crisis on Friday and heard from the UN special envoy on Myanmar, Christine Schraner Burgener, who warned against any moves to grant legitimacy to the junta.

"Your unity is needed more than ever on Myanmar," Burgener told the closed-door session. "The repression must stop."

She said that she is receiving some 2,000 messages a day from Myanmar urging international action.

"The hope they have placed in the United Nations and its membership is waning and I have heard directly the desperate pleas -- from mothers, students and the elderly," she said.

But diplomats said it was unlikely that the Security Council would approve any international measures against the junta such as a proposed global arms embargo.

The session called by Britain ended without any statement, although diplomats said consultations would take place next week on a proposed text.

"We'll be exploring further national sanctions and stand ready to consider possible measures under the UN Charter should the situation deteriorate further," British Ambassador Barbara Woodward said after the meeting.

"Any further measures would require agreement from all Council members," she said.

She was alluding to objections by several Council members including Russia, India, Vietnam and especially veto-wielding China, historically the main partner of Myanmar's military.

China's ambassador, Zhang Jun, said his country wanted to be a "friendly neighbour".

"We don't want to see instability, even chaos in Myanmar," he told reporters.

"The messages and measures of the international community should be conducive for the parties in Myanmar to bridge differences and resolve problems, and avoid escalating tensions or further complicating the situation."

In Myanmar's north, a number of people have crossed the border into India in a bid to escape the crackdown.

Indian police said nine people had crossed the 1,600-kilometre (1,000-mile) frontier -- three of whom were police officers who had refused to take part in putting down protests.

The junta has sought to stop news of the crackdown getting out, choking the internet and banning Facebook, the most popular social media platform in the country.

Friday also saw many parts of the country hit by power cuts for several hours, though it was not clear that this was a deliberate measure in a country where infrastructure is sometimes unreliable.

Government agencies attributed the outage to a "system breakdown".

Last month's coup brought a crashing halt to a decade-long experiment with democracy in Myanmar, which was previously under military rule for nearly five decades.

Suu Kyi's National League for Democracy won November elections by a landslide, but the military insisted the polls were rigged as a justification for seizing power.
