UNITED NATIONS // An estimated 5,000 Syrians are dying every month in the country's civil war and refugees are fleeing at a rate not seen since the 1994 Rwanda genocide, according to the United Nations.
"In Syria today, serious human rights violations, war crimes and crimes against humanity are the rule," said Ivan Simonovic, the assistant secretary-general for human rights, told the Security Council on Tuesday.
He added that "the extremely high rate of killings ... demonstrates the drastic deterioration of this conflict".
UN refugee chief Antonio Guterres said two-thirds of the nearly 1.8 million Syrian refugees known to the agency have fled since the beginning of 2013, an average of over 6,000 daily.
"We have not seen a refugee outflow escalate at such a frightening rate since the Rwandan genocide almost 20 years ago," he said.
UN humanitarian chief Valerie Amos said at least 6.8 million Syrians require urgent humanitarian assistance and accused the government and opposition of "systematically and in many cases deliberately" failing their obligation to protect civilians.
"This is a regional crisis not a crisis in Syria with regional consequences, requiring sustained and comprehensive engagement from the international community," Ms Amos said by videoconference from Geneva.
"The security, economic, political, social, development and humanitarian consequences of this crisis are extremely grave and its human impact immeasurable in terms of the long-term trauma and emotional impact on this and future generations of Syrians," she said. "We are not only watching the destruction of a country but also of its people."
Mr Simonovic said that since UN human rights chief Navi Pillay reported last month that at least 92,901 people had been killed between March 2011 when the conflict began and the end of April 2013, government forces and militias have moved to uproot the opposition in many areas including Qusair and Talkalkh, Aleppo, Damascus and its suburbs.
"Government forces carry on with indiscriminate and disproportionate shelling and aerial bombardments, using among other weapons tactical ballistic missiles, cluster and thermobaric bombs, all causing extensive damage and casualties if used in densely populated areas," he said.
"As a result, hundreds of civilians, including women and children were killed, thousands injured, and tens of thousands displaced," Simonovic said. "Many displaced in the parts of Homs and rural Damascus remain under siege and face miserable humanitarian conditions."
He said armed opposition groups have also committed acts of torture, abduction and kidnapping, sometimes along sectarian lines.
"Killings, violence and threats of reprisals against civilian populations perceived to be supportive of the government by armed opposition groups are escalating alarmingly," he said.
