Anti-war demonstrators [Occupy AIPAC] shout slogans as seen from the motorcade of US President Barack Obama as he is leaving after speaking during the AIPAC Policy Conference at the Washington Convention Center on March 4, 2012 in Washington, DC.

Obama urged Iran on Sunday to seek a diplomatic solution to the nuclear stand-off, reaffirming his backing for key ally Israel and saying there was “too much loose talk of war.” Addressing a pro-Israeli lobby group in Washington alongside Israeli President Shimon Peres, Obama said international sanctions were working and cautioned against saber-rattling as Iran moves closer to a nuclear weapon.
