WASHINGTON - US President Barack Obama said on Saturday that his administration still seeks dialogue with Iran over its nuclear issue but the Iran government has chosen isolation.

Obama made the remarks in a special video message in celebration of Nowruz, or "New Day," which marks the arrival of spring and the beginning of the New Year for millions in Iran and other communities around the world.

"We are working with the international community to hold the Iranian government accountable because they refuse to live up to their international obligations," Obama said in the message.
