An increase in the scale of fighting around Hodeidah in Yemen is blocking the port, on which aid and commercial depend, according to UN emergency relief coordinator Mark Lowcock.
Speaking last week to the UN Security Council, Lowcock said that all parties involved in the civil war needed to avoid further military activity around the Port of Hodeidah to protect its operations and the main supply of food and fuel coming into Yemen.
The port has been under the control of Iran-backed of Houthi rebels since 2014, who are fighting government forces backed by a Saudi-led coalition.
