U.S. President Barack Obama vowed on Sunday to step up efforts to eliminate Islamic State in Syria and prevent it from carrying out attacks like those in Paris, while European leaders urged Russia to focus its military efforts on the radical Islamists.
Speaking at a G20 leaders summit in Turkey, Obama described the killings in Paris claimed by Islamic State as an attack on the civilized world and said the United States would work with France to hunt down those responsible.
"The skies have been darkened by the horrific attacks that took place in Paris just a day and a half ago," Obama said after meeting Turkish President Tayyip Erdogan.
"We will redouble our efforts, working with other members of the coalition, to bring about a peaceful transition in Syria and to eliminate Daesh as a force that can create so much pain and suffering for people in Paris, in Ankara, and in other parts of the globe," he added, using an alternative name for Islamic State.
