Nuclear Summit: Obama Meets With Brokers Of Iran Deal [VIDEO]

U.S. President Barack Obama will speak Friday at the end of the second and final day of the nuclear security summit here attended by world leaders.

The U.S. leader said Thursday, from the summit’s sidelines, that in the wake of attacks in Brussels and elsewhere, there is “not only great urgency around the nuclear issue, but eliminating generally the scourge of terrorism.”

Obama’s fourth and final nuclear summit has come at a time of heightened concern about the possibility that Islamic State militants could set off radioactive bombs, and also about North Korea’s nuclear weapons development.

Some of the world leaders who attended a White House summit dinner Thursday were from countries that have been directly impacted by terrorist attacks.

At a State Department ministerial level dinner, U.S. Secretary of State John Kerry said nuclear security progress at times has been slow, and there remains an “enormous amount more to do.”
