Secretary of State Hillary Clinton joined French and British foreign ministers at the United Nations Security Council meeting, Tuesday, to press for a resolution condemning Syrian President Bashar al-Assad.
Clinton said action to end attacks on demonstrators in Syria would be different from the NATO-led attacks that forced out Moammar Gadhafi.
"I know that some members here may be concerned that the Security Council is headed toward another Libya," she said. "That is a false analogy."
"It is time for the international community to put aside our own differences and send a clear message of support to the people of Syria," Clinton added.
Some Security Council members hope to draft a new U.N. resolution demanding a halt to Syria's crackdown throughout the more than 10 months of uprising.
"We stand with you," Clinton said in an earlier statement.
"The longer the Assad regime continues its attacks on the Syrian people and stands in the way of a peaceful transition, the greater the concern that instability will escalate and spill over throughout the region," she continued.
Meanwhile, fighting continued Tuesday in the outskirts of Damascus, as Syrian military forces pushed back against army defectors and protesters using artillery.
The U.N. said 5,400 people have died since the crackdown began last March. An estimated 190 Syrians have been killed in the past five days.
