The violence took place as the military lost a fight over leadership of its UN mission in New York and the United States announced new sanctions targeting military conglomerates.

The man was killed in the city of Mandalay, witnesses and a doctor told Reuters by telephone.

In the 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.

Hundreds of protesters in the southeastern city of Dar Way also faced tear gas fired by police as they marched in protest against last month's military coup.

In all, at least 55 people have been killed since the coup on February 1st.

The UN human rights investigator on Myanmar, Thomas Andrews, has urged the Security Council, which meets later on Friday, to impose a global arms embargo and targeted economic sanctions on the Gionta.
