The U.N. Security Council on Wednesday condemned last week's massacre in Myanmar of more than 30 people that was blamed on junta troops.
The killings took place on Christmas Eve in eastern Kayah state. Pro-democracy rebels there have been fighting the military, which took over the government from the democratically elected administration in February.
In a statement released Wednesday evening, Security Council members "stressed the need to ensure accountability for this act." They also called for the immediate cessation of all violence and emphasized the importance of respect for human rights and of ensuring safety of civilians.
The statement said "at least 35 people" were killed in the attack, including four children and two members of the Save the Children charity staff.
The Security Council also "stressed the need for safe and unimpeded humanitarian access to all people in need, and for the full protection, safety and security of humanitarian and medical personnel."
Anti-junta fighters say they found more than 30 burned bodies, including those of women and children, on a highway in Kayah state following the attack. The two Save the Children employees had been missing, and the rights group confirmed Tuesday that they were among the dead.
Myanmar has been in chaos since the February coup, with more than 1,300 people killed in a crackdown by security forces, according to a local monitoring group.
Self-proclaimed People's Defense Forces have sprung up across the country to fight the junta and have drawn the military into a bloody stalemate of clashes and reprisals.
In the aftermath of the attack, Washington renewed calls for an arms embargo on the junta.
Western nations have long restricted weapons to Myanmar's military, which faced allegations of crimes against humanity — even during the pre-coup democratic transition — for a bloody campaign against the Rohingya minority.
The General Assembly voted in June to prevent arms shipments into Myanmar, but the measure was symbolic as it was not taken up by the more powerful Security Council.
China and Russia, which hold veto power on the Security Council, and neighboring India are the major arms providers to Myanmar.
