Yemen’s Shia Houthi rebels have made more gains in the city of Aden, despite air strikes by a Saudi-led coalition.
Fighting in the southern city has intensified as rebels and forces loyal to President Abdrabbuh Mansour Hadi battle for control.
Countries including China have stepped up efforts to evacuate their citizens amid the worsening humanitarian crisis.
The Red Cross has been given permission by the coalition to bring aid into Yemen by plane.
It says that two planes have been approved by the coalition. One will be a cargo plane carrying vital medical supplies, and the second a small passenger plane with aid workers.
Spokeswoman Sitara Jabeen said that the aim is to fly them both into the capital Sanaa on Monday.
