World powers have agreed to try to turn the crumbling partial truce in Syria in to a more comprehensive ceasefire.
The international Syria support group (ISSG )warned that the unravelling of the 11-week cessation of hostilities could lead to a return to all-out war.
Tuesday’s meeting in Vienna involved 21 countries and organisations in the ISSG, many of which have intervened directly or indirectly in Syria’s five-year civil war.
They include the US, UK, France, Germany, Saudi Arabia and turkey, which support the opposition, along with Russia and Iran, which back President Bashar Al-Assad’s government.
The ISSG has set a deadline of 1 august for the formation of a transitional government in Syria, leading to elections within 18 months.
