U.N. Secretary-General Ban Ki-moon is calling on Syrian forces and rebels opposed to President Bashar al-Assad to halt their fighting during the Muslim holy month of Ramadan, which begins Tuesday.
Ban says he is not looking for a negotiated truce, but rather a commitment from "every person holding a gun" in Syria to stop the violence as a gift to the Syrian people.
He says such a move can bring "hope and momentum toward peace," and reiterated that a Syrian-led political solution is the only way to end the "ever-worsening civil war."
More than two years of fighting have left as many 100,000 people dead and nearly 6 million others displaced within Syria or seeking refuge in neighboring countries.
Ban urged the international community to voice their support for the Syrian people, with the message that "yet more violence is not the way."
He also called on both sides in the conflict to immediately release detainees.
Meanwhile, Syria says it has invited U.N. officials to Damascus to discuss the alleged use of chemical weapons in the country. However, Syria's ambassador to the U.N., Bashar Jaafari, made clear Monday that the talks would be limited to a specific instance in which the government says rebels used chemical weapons, and not the broad investigation the U.N. wants to carry out.
Ban welcomed the offer that would send Angela Kane, the U.N. official in charge of disarmament, along with Ake Sellstrom, who is leading the U.N.'s chemical weapons investigation for Syria. But he says he remains "seriously concerned" about the allegations.
Sellstrom is due in New York this week to brief Ban on what his team has found in investigations in neighboring countries and from information provided by other U.N. members.
