An Iranian ship carrying 2,500 tons of medical supplies, relief workers and peace activists from several countries left the Southern Iranian port city of Bandar Abbas for Yemen’s Red Sea port of Hudaydah, Iran’s Fars news agency reported.
The Iranian Red Crescent Society (IRCS) has been trying to dispatch humanitarian aid to Yemen by sea and air, but has failed due to Saudi Arabia's full blockade of the war-ravaged country.
