SANA’A, YEMEN – NOVEMBER 03: Yemeni children who were affected by the ongoing war wait to receive free lunch meal from a charity food distribution center on November 03, 2018 in Sana’a, Yemen. The United Nations Children’s Fund regional director says local Yemeni authorities are making it “impossible” for the delivery and distribution of much-needed humanitarian aid in Yemen and warned that impeding relief efforts could accelerate famine conditions.
