US offers Iran a 'new beginning'

President Barack Obama has offered to "extend a hand" to Iran

US President Barack Obama has offered "a new beginning" of diplomatic engagement with Iran in an unprecedented videotaped message.

"My administration is now committed to diplomacy that addresses the full range of issues before us," Mr Obama said.

His message was released to coincide with the festival of Nowruz - when Iranians mark the arrival of spring.

Relations between Iran and the US have been strained over Tehran's controversial nuclear activities.

The US fears Iran's nuclear programme is a cover to build atomic weapons, a charge Iranian officials deny.

Warning

In his message, President Obama said he wanted "to speak directly to the people and leaders of the Islamic Republic of Iran".

He said his administration was committed "to pursuing constructive ties among the United States, Iran and the international community".

"With the coming of a new season, we're reminded of this precious humanity that we all share. And we can once again call upon this spirit as we seek the promise of a new beginning," the message said.

But Mr Obama warned: "This process will not be advanced by threats. We seek instead engagement that is honest and grounded in mutual respect."

Mr Obama has talked of engagement with Iran but has not made clear how that might take place.

Shortly after coming to office in January, he said "if countries like Iran are willing to unclench their fists, they will find an extended hand from us".

However, earlier this month he extended sanctions against Iran for one year, saying it continues to pose a threat to US national security.
