Iran has called for all sides in Yemen's war to join UN-sponsored peace talks and accused Saudi Arabia of worsening the conflict with its military intervention against the Arab impoverished country.

In talks with visiting UN envoy Ismail Ould Cheikh Ahmed on Wednesday, Iranian officials including Foreign Minister Mohammad Javad Zarif backed his efforts to resolve the conflict.

Stressing the UN role "in finding a political solution in Yemen," Zarif called for "the participation of all Yemeni groups" in talks Cheikh Ahmed is hoping to convene in Geneva this month, the IRNA news agency reported.

In separate talks with Cheikh Ahmed, Iran's deputy foreign minister told the envoy Saudi Arabia's intervention was making security worse.

"For the Islamic Republic of Iran, the security of Yemen, Saudi Arabia and the region are important," the ISNA news agency quoted Hossein Amir Abdollahian as saying.

"But Saudi Arabia cannot endanger the security of others to provide its own security," he said.

Cheikh Ahmed for his part praised Iran as "an important and influential country in the region" which has "a determining role in the fight against terrorism," IRNA reported.

Yemen has been since March 26 under brutal aggression by Saudi-led coalition. Thousands have been martyred and injured in the attack, with the vast majority of them are civilians.

Riyadh launched the attack on Yemen in a bid to restore power to fugitive Hadi who is a close ally to Saudi Arabia.

The humanitarian crisis in Yemen has been identified by the United Nations as one of the world's worst, with 80 percent of the country's population on the brink of famine.
