British Prime Minister David Cameron has reportedly commenced talks with world leaders attending the 10th G-20 Summit being held in the Turkish resort town of Antalya on Sunday and Monday.
The focus of Cameron's talks will be on how to combat terrorism and bring peace to Syria in the wake of Friday night's terrible terror strikes in French capital Paris that left 129 people dead and several hundred others injured.
The Syria and Iraq-based Islamic State has claimed responsibility for the killings and French President François Hollande has declared it to be an act of war, while imposing a state of emergency across France.
According to The Guardian, the G20 meeting is due to address terrorism and migration at a dinner on Sunday evening, before discussing climate change, corporate tax avoidance and the overall state of the world economy on Monday.
The discussions will now be dominated by the growing concern that Isis is moving beyond its sanctuary in northern Syria and transforming into a global terrorist network capable of wreaking devastation in western cities.
Cameron is due to hold bilateral talks with Vladimir Putin on Monday, his first since the last G-20 in Brisbane, Australia, a year ago.
Meanwhile, Indian Prime Minister Narendra Modi has had a meeting with Putin on the sidelines of the G-20 Summit and just before BRIC leaders gathered for a discussion on issues of pressing interest to their region.
Modi is meeting leaders of BRICS countries-Brazil, Russia, China and South Africa-to review the progress of their two initiatives launched last year, the BRICS Bank and the Contingent Reserve Arrangement.
