Denmark's Prime Minister Helle Thorning-Schmidt makes a phone call as she leaves after the closing session of the Nuclear Security Summit in The Hague, Netherlands, Tuesday March 25, 2014. Thirty-five countries pledged Tuesday to turn international guidelines on nuclear security into national laws, a move aimed at preventing terrorists from getting their hands on nuclear material. Tuesday's initiative following a two-day summit of leaders also commits countries to open up their security procedures to independent review, a further step toward creating an international legal framework to thwart nuclear terrorism, said a joint statement from the Netherlands, the United States and South Korea.
