Thousands of Syrians have died in the violent uprising. Opposition groups estimate the death toll to range from at least 12,000 to more than 14,000.
Al-Assad's government lashed out at Washington, saying it "is continuing its blatant interference in the internal affairs of Syria, its open support for terrorists, covering up terrorists' crimes, distorting facts about Syria at the United Nations, and extorting countries and the international community to beleaguer Syria," the state news agency reported Wednesday.
At least 60 people were killed Tuesday, the Local Coordination Committees said. Among the victims was a family of six, including an infant. They were killed in Aleppo province when a shell landed on their home, the opposition group said.
The state-run new agency said 36 "martyrs from the army and law enforcement forces" were buried Tuesday.
