Leaders of the world's 20 major economies (G20) have convened in Antalya, a heavily guarded Turkish resort on the Aegean Sea coast, for a two-day summit, with the refugee crisis dominating the start of the meeting. 
In a draft communique, leaders have agreed that the refugee crisis is a global problem that must be addressed in a coordinated way.
"We call upon all states to contribute to responding to this crisis, and share in the burdens associated with it," it reads, according to Reuters.
The draft communique states that tackling the refugee crisis means proactive measures, "including through refugee resettlement, other forms of humanitarian admission, humanitarian aid and efforts to ensure that refugees can access services, education and livelihood opportunities". 
The meeting is taking place in the shadow of theParis assaults claimed by the Islamic State of Iraq and the Levant (ISIL) group which left at least 129 people dead and more than 350 others injured, 99 of them critically.
Although the G20 usually focuses on economic issues, the president of host country Turkey, Recep Tayyip Erdogan, has urged world leaders to prioritise the battle against ISIL, saying the attacks in Paris proved that the time for words was now over.
Erdogan said: "We are confronted with a collective terrorism activity around the world.  As you know, terrorism does not recognise any religion, any race, any nation, or any country".
Following his statements, US President Obama affirmed Washington's support for Paris in the wake of the attacks, saying: "We stand in solidarity with them [France] in hunting down the perpetrators of this crime and bringing them to justice."
Focus on ISIL
Al Jazeera's Bernard Smith, reporting from Antalya, said security preparations for the summit amounted to "the most intensive security operation" that Turkey has had to carry out.
"It's one of those rare occasions where so many leaders are gathered together in one event," he said.
French President Francois Hollande cancelled his attendance at the summit, and sent Laurent Fabius, the Foreign Minister, to represent him.
