UN Secretary-General Ban Ki-moon has called on major powers to stop sending weapons to all sides in Syria, as he opened the annual UN General Assembly summit.
"I appeal to all states to stop fueling the bloodshed and to end the arms flows to all parties," Ban told world leaders at the UNGA opening in New York on Tuesday.
The UN chief also called on Syrian President Bashar al-Assad and the opposition - and "all those in this hall with influence over them" - to work immediately to arrange a second Geneva conference aimed at reaching a political solution to the crisis that has wracked Syria for more than two years.
"Military victory is an illusion. The only answer is a political settlement," he said.
Ban said the response to last month's "heinous use of chemical weapons" outside Damascus "has created diplomatic momentum - the first signs of unity in far too long".
