(Reuters) - Police in Myanmar on Friday opened fire on protesters against last month's military coup, killing one man, as international condemnation rained down on the junta and the U.N. special envoy on Myanmar urged the Security Council to act.
Christine Burgener called on the council for "unified support, action", asking "how much more can we allow the Myanmar military to get away with?", following the deaths of dozens of civilian protesters this week.
She said the situation in Myanmar was moving toward "an acute humanitarian crisis".
Activists demanding the restoration of the elected government of veteran democracy champion Aung San Suu Kyi held more demonstrations in several towns and cities, with thousands marching peacefully through the second city of Mandalay.
"The stone age is over, we're not scared because you threaten us," the crowd chanted.
Police opened fire and one man was killed, witnesses and a doctor told Reuters by telephone.
An official from Suu Kyi's National League for Democracy (NLD) was also stabbed to death along with his 17-year-old nephew in an apparent mob attack in the central Magwe region, local media reported.
Myanmar Now cited the son of the official, who survived the attack, as saying 25 supporters of the military-backed Union Solidarity and Development Party set upon them with knives.
The party did not immediately respond to a request for comment.
In the main city of Yangon, police fired rubber bullets and stun grenades to disperse protesters who had been joined by about 100 doctors in white coats, witnesses said.
Crowds also gathered in Pathein, to the west of Yangon, and in central Myingyan, where dozens of women in straw hats held up signs calling for Suu Kyi's release, witnesses said.
A spokesman for the ruling military council did not answer telephone calls seeking comment.
Thousands also rallied in the southeastern Karen state, accompanied by fighters from the Karen National Union (KNU), an ethnic armed group engaged in a long-running war with the military.
During the rally - the strongest indication yet of support for the anti-coup movement from one of the country's myriad ethnic armed groups - KNU troops flashed the three-finger salute popularized by protesters and handed out water bottles.
The KNU said in a statement it would not tolerate attacks on peaceful protesters by the army.
"People in urban areas, ethnic armed groups and the international community must work together until the military dictatorship falls," it said.
On Thursday, police broke up rallies with tear gas and gunfire in several cities but the crackdown was more restrained than on Wednesday, when the United Nations said 38 people were killed in the bloodiest day of protests.
In all, at least 55 people have been killed since the Feb. 1 coup.
U.N. human rights chief Michelle Bachelet demanded the security forces halt what she called their "vicious crackdown on peaceful protesters". Bachelet said more than 1,700 people had been arrested, including 29 journalists.
The International Federation of Red Cross and Red Crescent Societies said some Red Cross volunteers had been injured and wrongfully arrested and Red Cross ambulances had been damaged.
The military seized power saying that the NLD's landslide victory in an election in November was fraudulent. The electoral commission has said the ballot was fair.
The junta has promised new elections but not given a date. Activists have rejected that and demand the release of Suu Kyi, who has been in detention since the coup.
DISOBEDIENCE
Singapore has been the most outspoken of Myanmar's neighbours and its foreign minister, Vivian Balakrishnan, said it was a "national shame" for armed forces to use weapons against their people.
But condemnation of the coup and subsequent violence has come largely from the West, with Asian nations, including India, mostly more restrained. The junta can count on some support from Russia and China - a major investor - at the United Nations.
The military has weathered isolation and sanctions during previous eras of army rule and has indicated it will not be swayed this time around.
The U.N. human rights investigator on Myanmar, Thomas Andrews, urged the Security Council to impose a global arms embargo and targeted economic sanctions on the junta.
The United States has told China, which has declined to condemn the coup, that it expects it to play a constructive role. China has said stability is a top priority.
The military, which ruled directly for nearly 50 years until it embarked on a tentative transition to democracy a decade ago, has been struggling to impose its authority on a country where many people abhor the thought of a return of army rule.
A civil disobedience campaign of strikes running parallel with the protests has been supported by many government workers including a trickle of policemen.
Indian security forces meanwhile stepped up border patrols to stop any more people entering, Indian officials said. About 20 policemen crossed into India this week fearing persecution for disobeying orders to enforce the crackdown.
"As of now, we are not letting anybody enter," Maria Zuali, a government official in Mizoram state, told Reuters.
The move follows the defection over the border of some low-ranking Myanmar police officers who were unwilling to obey orders to suppress demonstrations.
More than 10 Myanmar diplomats in foreign missions have also declared their support for the pro-democracy campaign, the Irrawaddy news outlet reported. In Washington, it was unclear whether Myanmar's embassy was still representing the junta.
In New York, a clash over who represents Myanmar at the United Nations was averted after the junta's replacement quit and the Myanmar U.N. mission confirmed that Ambassador Kyaw Moe Tun remained in the job.The junta fired Kyaw Moe Tun on Saturday after he urged countries at the U.N. General Assembly to use "any means necessary" to reverse the coup.
