BELEK, TURKEY ¨C U.S. President Barack Obama vowed on Sunday to step up efforts to eliminate Islamic State and prevent more attacks like those in Paris, while urging Russia¡¯s Vladimir Putin to focus on combating the jihadist group in Syria.
A White House official said Obama and Putin agreed in a 35-minute meeting on the sidelines of a G-20 summit in Turkey on the need for a political transition in Syria, saying events in Paris had made it all the more urgent.
The two-day summit brings Obama and fellow world leaders just 500 km (310 miles) from Syria, whose 4?-year conflict has transformed Islamic State into a global security threat and spawned Europe¡¯s largest migration flows since World War II.
