WASHINGTON (AP) — The global anxiety sparked by a series of deadly attacks in Paris by the Islamic State group has given new urgency to President Barack Obama’s upcoming talks with world leaders.

The Islamic State group has taken root in Syria. The crisis in that country was already high on the agenda for the meeting of 20 leading industrialized and emerging-market nations. But the violence in Paris that killed at least 127 people will dramatically change the dynamic of the talks in Antalya, Turkey. The seaside resort sits just a few hundred miles from the Syrian border.

French President Francois Hollande says the Islamic State group was behind the attacks. The extremists claimed responsibility on Saturday. The U.S. has not commented on who is responsible for the carnage.
