Speaking after a rare NATO meeting on Iran and Iraq in which the United States briefed its allies about last Friday's drone strike, Stoltenberg also called for a de-escalation of tensions, echoing the statements of some European leaders."We are united in condemning Iran's support of a variety of different terrorist groups," Stoltenberg said. "At the meeting today, allies called for restraint and de-escalation. A new conflict would be in no one's interest. So Iran must refrain from further violence and provocations."
