Syrian rebels say they are willing to lay down their arms – if the Syrian army pulls tanks, artillery and heavy weapons out of opposition areas.
The offer was made by a spokesman for Free Syrian Army commanders and is the biggest step the rebels have taken towards a ceasefire since the uprising began more than a year ago.
The United Nations estimates some 9,000 people have been killed by government forces since then. For its part, Damascus says it has lost 3,000 men.
In a separate move, one opposition group issued a demand for more electoral reform ahead of a parliamentary ballot due to be held in May.
