World leaders vowed a vigorous response to the Islamic State group's terror spree in Paris as they opened a two-day meeting in Turkey on Sunday, with President Barack Obama calling the violence an "attack on the civilized world" and Russian President Vladimir Putin urging "global efforts" to confront the threat, AP reported. But beyond the tough talk and calls for action, there was little indication of how leaders intended to escalate the assault on the extremist group.
