Munich, Rabi'I 21, 1434, Feb 2, 2013, SPA - US Vice President Joe Biden on Saturday offered talks to Iran on ending its nuclear programme, called Syria's president "a tyrant" who must go, and praised the idea of a transatlantic free trade zone. Biden, on his first trip abroad since President Barack Obama started his second term in January, outlined some of the administration's priorities for the next four years. Speaking at the annual Munich Security Conference, he said he did not want to "steal the president's thunder" ahead of Obama's State of the Union address next week. However, he said some of the key US objectives would include nuclear non-proliferation, combating climate change and extreme poverty, and promoting free trade, according to a report of DPA. Another goal was "maintaining our commitment to the elusive, elusive but essential, goal of Middle East peace," he said. Biden reiterated an offer to Iran of bilateral talks on ending its nuclear programme. "There is still time, there is still space for diplomacy to succeed," Biden said. "The ball is in the government of Iran's court. It is well past time for Iran to adopt a serious good-faith approach to negotiations." On war-torn Syria, Biden said the "tyrant" President Bashar Al-Assad "is no longer fit to lead the Syrian people, and he must go." --SPA 13:58 LOCAL TIME 10:58 GMT www.spa.gov.sa/1074307
