A senior Iranian official has called for an immediate end to ongoing conflicts in Yemen and Syria, saying these countries are bogged down in critical conditions.

“The war in Yemen and Syria must end quickly and we must exhaust [our potential] in favor of establishing peace,” Ali Akbar Velayati, the foreign affairs' adviser to Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei, said in a meeting with United Nations Deputy Secretary General Jan Eliasson in Tehran on Tuesday.

“Terrorists from more than 80 world countries are present in the [Middle East] region and have engaged in a war with legitimate governments in the region through forming extremist groups,” he added.

Velayati also said that Saudi Arabia is conducting airstrikes on residential areas across Yemen and damaging the country’s infrastructure.

Yemen has been under military strikes on a daily basis since Saudi forces launched their military aggression against their southern neighbor on March 26, in a bid to undermine the Houthi Ansarullah movement and restore power to fugitive former Yemeni President Abd Rabbuh Mansour Hadi, a staunch ally of Riyadh.

The UN envoy, for his part, pointed to the critical situation in the Middle East and urged more efforts to establish peace and security in the region.

Eliasson said the UN would spare no efforts to improve peace and security in the region.

UN inaction on Yemen war unacceptable

Meanwhile, Secretary of Iran’s Supreme National Security Council (SNSC) Ali Shamkhani said the UN failure to show serious reaction to foreign intervention in Yemen is "unacceptable.”

In a meeting with Eliasson on Tuesday, Shamkhani added that the United Nations refrained from taking decisive action to end military aggression, arms supply and financial aid to terrorists as well as suppression of Muslims in the occupied Palestinian lands which raised serious questions about the UN’s performance.

The SNSC secretary added that Iran has staved off the spread of terrorism and genocide in Syria and Iraq by supporting the legal and popular governments of Syria and Iraq.

“Western countries must change their approach toward the establishment of lasting security in the region through real fight against terrorism,” Shamkhani said.

The UN deputy chief, for his part, hailed Iran’s efforts in settling refugees over the past decades and said Iran’s experience is needed for dealing with refugee crises in other countries.

Political solutions needed

Iran’s Foreign Minister Mohammad Javad Zarif also met with the UN official, stressing the importance of solving ongoing crises in the region through political approaches.

He said that the intensity of the regional crises is directly linked to the conduct of political leaders in the region.

"The realities of the region must be discussed in a realistic way,” Zarif said.

He added that all world countries must prioritize countering threats posed to the regional countries.
