Iran on Wednesday welcomed a US declaration of support for a peace process in Yemen in order to help put an end to the Saudi-led aggression, one year after the announcement of a United Nations-mediated ceasefire.

On Tuesday, Timothy Lenderking, the special representative of the US for Yemen, called on Iran to support efforts to reach peace in the country.

"We also would like to see the Iranians show support for the political process that we hope is coming," Lenderking said.

He noted favorably that Iran welcomed the ceasefire a year ago.

Iranian Foreign Ministry Spokesperson Nasser Kanaani described Lenderking's call as "gratifying", underlining that Tehran had been "striving for a peace process since the beginning of the war."

This comes after last month, Iran and Saudi Arabia agreed to restore diplomatic relations and reopen missions in respective countries after a series of talks brokered in Beijing, China under the auspices of Chinese President Xi Jinping.

Following the agreement, UN Spokesperson Stephane Dujarric indicated that the United Nations hopes that the renewal of diplomatic ties between Iran and Saudi Arabia will positively impact the situation in Yemen.

"In Yemen, we have a situation that is fragile … We hope this agreement will have a positive impact on this situation and others," Dujarric told a briefing.

He added that it is no surprise that the tension arising from the Iranian-Saudi relationship reflected negatively on the region and impacted it as a whole. 

Nearly a decade of Saudi-led aggression has claimed hundreds of thousands of lives and triggered what the United Nations has described as the world's worst humanitarian crisis.
