The UN General Assembly adopted a resolution (PDF) Dec. 21 to establish an independent panel to investigate possible war crimes in Syria. The resolution, approved by a vote of 105 to 15 with 52 abstentions, will establish an "International, Impartial and Independent Mechanism to Assist in the Investigation and Prosecution of Those Responsible for the Most Serious Crimes under International Law Committed in the Syrian Arab Republic since March 2011." The mechanism will work closely with the Independent International Commission of Inquiry on Syria, established by the UN Human Rights Council in 2011. The resolution:

Pro-Assad forces are on the verge of capturing all remaining opposition-held areas of Syria's largest city Aleppo, with fears of death or detention for tens of thousands of civilians. Regime troops and allied Iranian-led foreign and paramilitary forces, supported by intense Russian air-strikes, took all but a few remaining districts on Dec. 12. Claims circulate of the execution of scores of civilians in districts that have fallen to pro-regime forces. Residents and activists spoke of widespread detention of fighting-age men. UN Secretary-General Ban Ki-moon's office issued a statement voicing alarm over "reports of atrocities against a large number of civilians, including women and children, in recent hours in Aleppo." UN humanitarian adviser Jan Egeland said Assad and Russia will be held "accountable for any and all atrocities that the victorious militias in Aleppo are now committing."

Expressing "outrage" at the escalation of violence in Syria, and particularly Aleppo, the UN General Assembly on Dec. 9 adopted a resolution demanding an immediate and complete end to all attacks on civilians, as well as a lifting of all sieges on cities and towns. The Canada-sponsored resolution was adopted by a vote of 122 in favor, 13 against and 36 abstentions. The text also expressed grave concern at the continued deterioration of the humanitarian situation in the country and demanded "rapid, safe, sustained, unhindered and unconditional humanitarian access throughout the country for UN...and all humanitarian actors."

A group of German lawyers have filed a criminal complaint against Syrian dictator Bashar Assad on charges of war crimes and crimes against humanity. Speaking at a press conference in Berlin on Nov. 28, attorney Mehmet Daimaguler said they were optimistic the German federal prosecutor will open a formal investigation following their complaint. German law allows prosecutions under the principle of universal jurisdiction, holding that nations can charge foreigners for grave crimes committed abroad. The lawyers cited Amnesty International reports and individual accounts by asylum-seekers in Germany in arguing overwhelming evidence of multiple atrocities committed by Assad in Aleppo between April and November. "We're experiencing genocide in Aleppo in slow motion," Daimaguler said, citing the targeted bombing of hospitals, cluster bombs on civilians and forced expulsion.

Backed by unrelenting Russian air-strikes, Syrian pro-regime forces are now making rapid advances into rebel-held eastern Aleppo. The fall of the city's Masaken Hanano district is a harsh symbolic blow, as it was the first area the rebels took in the summer of 2012. There is a mass exodus of residents ahead of the regime forces. Up to 20,000 have been displaced just over the past 72 hours, the Red Cross said Nov. 29. (BBC News, BBC News, AFP) But there is really nowhere to run. "This week I've changed locations three times," a medic in east Aleppo said via social media. "In the shelter, we had dead people who we couldn't take out because the bombardment was so intense." (Reuters; Orient Net) Regime forces are apparently continuing to use chemical weapons. The activist Aleppo Media Center tweeted disturbing photos of what it said were victims of a chlorine attack in east Aleppo.

According to official John McKissick at the United Nations High Commissioner for Refugees on Nov. 24, members of the Rohingya community have been subjected to numerous atrocities by troops in Burma, including execution, rape, starvation and forced displacement. McKissick said the widespread violence is part of an ongoing effort by the Burmese government to "ethnically cleanse" the Muslim minority group from the country. Speaking to the BBC from the UNHCR headquarters in Cox's Bazar, Bangladesh, McKissick said the latest increase in violence against the Rohingya is in response to the murder of nine border guards in Burma on Oct. 9, which some Burmese politicians have blamed on a Rohingya militant group.
