AP � The head of the U.N. agency monitoring Iran�s nuclear deal with the U.S. and five other nations says Tehran is living up to its end of the agreement � comments that indirectly oppose President Donald Trump�s view.

The U.S. president refused last month to certify Iran�s compliance, saying the benefits Tehran is getting from the deal are not proportional to its concessions.

Iran limited its nuclear program in exchange for an end to nuclear-related sanctions, but legislation now is pending before Congress that would attach additional conditions for existing U.S. sanctions relief � a move Tehran says would violate the pact.

Speaking Thursday, International Atomic Energy Agency chief Yukiya Amano told the IAEA�s 35-nation board that the �commitments being undertaken by Iran are being implemented.�
