Iran PressMiddle East: The Yemeni National Oil Company said in a statement that all of the ships were licensed by the United Nations, adding that the Saudi coalition's action to seize ships carrying Yemeni fuel is against international law.

The Saudi coalition has repeatedly seized ships carrying fuel, food and medical equipment in Yemen.

Yemen has been facing severe shortages of fuel, food and medical equipment for the past six years due to the siege of the Saudi coalition.

Mark Lowcock, the UN Under-Secretary-General for Humanitarian Affairs, recently stated that Yemen is facing the worst humanitarian catastrophe in history.

Saudi Arabia, with the support of the United States, the United Arab Emirates and several other countries, has been invading Yemen since March 2015. The outbreak of war by Saudi Arabia and its allies in Yemen has so far killed tens of thousands and displaced millions of Yemenis.

The Saudi military aggression has also left the poor country of Yemen severely short of food and medicine. 219
