The coalition of international NGOs, political leaders and the global campaigning organisation Avaaz, is demanding that leaders commit to a plan that provides robust support to Syria’s neighbours, who have hosted the vast majority of refugees since the conflict erupted in 2011.

Emma Ruby-Sachs, Acting Executive Director of Avaaz, said:
"This weekend our governments have the power to come together and commit to resettle refugees, provide robust humanitarian aid, protect civilians, and broker real talks for a political transition. If they ignore the call of their citizens, there may be no Syria left to save."
The coalition warns that the spillover effect of brutality is being felt keenly by Turkey and Lebanon in particular.
It’s an impact that is also being felt in France today, still reeling from the multiple co-ordinated gun and bomb attacks across Paris on Friday night, with 127 dead.
French President Francois Hollande has cancelled his participation in this weekend's G20 meeting, which will be hosted by Turkey.
The Islamic State claimed responsibility for last night’s assault with Mr Hollande has calling it “an act of war”.
France is a founding member of the US-led coalition waging air strikes against Islamic State in Syria and Iraq.
Leaders of the Group of 20 major economies (G20), including Russia, the United States, UK and China, are to meet on Sunday and Monday in the Mediterranean resort of Antalya. As an economic forum, the agenda is expected to primarily discuss global economic issues.

However, in light of the recent terror attack in the heart of one of its member states, it’s expected that talk will also turn to the wider security implications of the ongoing conflicts in the Middle East.
Indeed, Turkey, a member which has taken in more than two million refugees fleeing from neighbouring Syria and Iraq, wants the heads of state to also discuss the failed international leadership in the region. Unrelenting unrest on Turkey’s southern borders is continuing to destabilise the country, and the wider Middle East.
"Our inclusion of issues of Iraq and Syria to the G20 agenda is not against the primary objectives of the platform," Turkish President Recep Tayyip Erdogan told a business meeting in the capital Ankara.
The four year continuing melee of violence and political impasse in Syria is also being seen as a significant factor behind Europe's current migrant crisis.
More than 750,000 migrants are estimated to have made the arduous journey across the Mediterranean Sea to Europe this year alone. It's Europe's largest migration flow since World War Two, and there is still no agreement on how to resettle those who make it.
For some experts, any sustainable solution must also include multilateral leadership on Syria itself, and its closest neighbors.
The coalition's campaign is backed by a new report from the Middle East Investment Initiative called 'The Middle East Recovery Plan: Act Now or Pay Later', which suggests that a long-term investment geared towards economic development, is what is required in the region.
The report also draws the connection between the necessity of economic growth and attempts to decrease incentives for people getting drawn into extremism.
Turkey is expected to press G20 leaders for joint responses to the refugee crisis and Islamic State threat on its borders.
The G20 countries account for 85 percent of the world economy, 75 percent of world trade and two-thirds of the world's population.
