TEHRAN (Tasnim) � Iranian Foreign Minister Mohammad Javad Zarif in separate phone conversations discussed the ongoing crisis in Yemen with the foreign ministers of Russia and China.

In phone calls on Saturday, Zarif exchanged views with Russian Foreign Minister Sergey Lavrov and Chinese Foreign Minister Wang Yi on the crisis in Yemen, the humanitarian conditions, and the ways to dispatch aid to the war-torn country.

In recent days, Iran has intensified its diplomatic moves to facilitate the delivery of humanitarian aid.

Earlier on Friday, Iranian Deputy Foreign Minister Hossein Amir Abdollahian in a phone conversation with his Russian counterpart Mikhail Bogdanov strongly criticized Riyadh for blocking the dispatch of humanitarian aid to Yemen, and described the situation in the Arab country as �the humanitarian catastrophe of the century�.

Despite UN�s efforts, Saudi Arabia is causing troubles both in the course of dispatching humanitarian aid and adherence to the ceasefire, he said.

The Iranian diplomat further called on the international community to break the siege on the Arab country.

Amir Abdollahian also had a phone conversation with the special representative of UN�s secretary-general Ismail Ould al Sheikh Ahmed, during which the Iranian diplomat asked for the acceleration of UN�s relief operation in Yemen.

On March 26, Saudi Arabia and some of its Arab allies began to launch deadly air strikes against the Houthi Ansarullah movement in an attempt to restore power to the fugitive former President Abd Rabbuh Mansour Hadi, a close ally of Riyadh.

Earlier on May 7, Saudi Arabia announced a five-day 'humanitarian' ceasefire, to which Ansarullah movement and the Yemeni army consented. The ceasefire has started on Tuesday.

Iran has tried three times to send humanitarian aid to Yemen, but Saudi fighter jets have refused aid planes landing in Sana'a airport.

However, Iran dispatched a cargo ship carrying humanitarian assistance to Yemeni port of Hodeida on Monday evening, which is due to arrive at the war-torn country on May 30.
