(VOVworld) – 4 air strikes by the Saudi-led coalition on Sunday hit the Yemeni Presidential Palace in Sana’a and a nearby hill where Houthi reinforcements are preparing to seize the oil-rich Marib province in eastern Yemen. This is the first time Sana’a has been hit coalition air strikes since its campaign against Houthi rebels began last week.

The same day, coalition aircraft dropped medical supplies for forces loyal to Yemen’s President Hadi in the southern city of Daleh, after the Houthis had prevented an international humanitarian group from entering the city.
