The Saudi-led coalition fighting in Yemen said on Wednesday it would reopen a key Red Sea port and Sanaa airport to aid, after a more than two-week blockade following a missile attack on Riyadh.
The coalition said it would reopen Hodeida port to receive "urgent humanitarian and relief materials" and Sanaa airport to UN aircraft from midday on Thursday.
It did not specify when or if it would ease a blockade on commercial traffic.
Hodeida, which is controlled by Houthi rebels backed by Iran, is a key conduit for much-needed food and medicine imports to Yemen.
The coalition imposed a total blockade of Yemen's ports and airports two days after the Houthis fired a missile at Saudi Arabia on November 4.
The missile was intercepted near Riyadh's King Khalid International Airport, sparking a war of words between Tehran and Riyadh, which accused Iran of "direct aggression" and supplying arms to the Houthis.
The United Nations Security Council on November 9 called for the blockade to be lifted, warning that otherwise Yemen would face "the largest famine the world has seen for decades".
The Houthi government on Tuesday announced the country's main international airport was fully functional again a week after a Saudi-led air strike destroyed the facility's navigation system.
The airport had been open to only select humanitarian flights.
Allied with Yemeni strongman Ali Abdullah Saleh, Houthi rebels control the capital Sanaa along with much of northern Yemen.
The UN Food and Agriculture Organisation (FAO) says Yemen is highly dependent on imported wheat for its basic needs.
