The International Committee of the Red Cross has turned down a call from Saudi Arabia for aid workers to leave parts of Yemen that are being hit in airstrikes. The ICRC’s Sana’a spokeswoman said they will continue to operate in all regions of the country to reach the civilians affected by the conflict. The official said their mission often necessitates crossing frontlines and securing access to combat zones. Saudi Arabia has asked the United Nations to move aid workers away from government-held areas. The UN aid chief Stephen O’Brien also rejected the request and reminded Riyadh of its obligations to allow humanitarian access in Yemen. The UN has had several disputes with Saudi Arabia over aid access in Yemen, where 80 percent of the population is facing dire food shortages.
