Israel's prime minister says a decade after the Sept. 11 attacks, Iran's nuclear program must be stopped and that the possibility of extremists getting atomic weapons is a real threat.
Benjamin Netanyahu spoke at a memorial Sunday marking the anniversary of the attacks in the U.S.
In the speech, he repeated a long-standing plea to the world to prevent Iran from developing nuclear weapons. Israel considers Iran a serious threat because of its nuclear program, support for anti-Israel militants and frequent references to Israel's destruction.
Netanyahu said the "the possibility that the world's most dangerous weapons will fall into the hands of the world's most dangerous regimes is too real."
