AKIPRESS.COM - Leaders of the world's 20 major economies (G20) have pledged a renewed fight against the Islamic State of Iraq and the Levant (ISIL) group, but offered little details on how the strategy would change.

The leaders are meeting in Antalya, a heavily guarded Turkish resort on the Aegean Sea coast, for a two-day summit also expected to be dominated by the refugee crisis, reports Al Jazeera.

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 Friday's assaults in Paris, claimed by ISIL, proved that the time for words was now over.

The attacks left at least 129 people dead and more than 350 others injured, 99 of them seriously.

ISIL also claimed responsibility for a bombing in Beirut, Lebanon that killed at least 43 people on Thursday.

"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," he said.

US President Barack Obama, meanwhile, 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."

He pledged to "redouble" US efforts to eliminate ISIL, but offered no details about what the US or its coalition partners might do to step up its assault against the group.
