WASHINGTON (AFP) - US President Barack Obama said on Saturday that diplomacy was the best option to deal with Iran's contested nuclear programme, two days after the conclusion of a framework agreement with Teheran.

Iran and six world powers determined the outlines of a landmark agreement which would curb Iran's nuclear program and potentially lift economic sanctions.

As Obama gears up to sell US sceptics on the deal, he said he is convinced talks are the best way forward.

"As President and Commander in Chief, I firmly believe that the diplomatic option - a comprehensive, long-term deal like this - is by far the best option," Obama said in his weekly address.
