The Saudi-led coalition said on Tuesday that eight ships headed to Yemeni ports, including Hodeidah, have been granted permission.
Last week four ships headed to Yemen’s Hodeidah were granted access to the port.
Yemen's warring parties have confirmed their willingness to restart negotiations after a two-year hiatus, the UN special envoy for Yemen said even as fighting raged along the country's west coast over a key port city.
Martin Griffiths told the UN radio late on Thursday that he plans to bring the Houthis, and the country's internationally recognized government to the negotiating table within the next few weeks "at the very latest."
He said he hopes the UN Security Council will come up with a plan next week and present it to the Yemenis.
