Yemen’s Iran-aligned Houthi movement accused the Saudi-led coalition of carrying out retaliatory air strikes on Saturday that killed at least 30 people including civilians, in the latest flare-up of a five-year war. The United Nations office in Yemen said preliminary field reports indicated that “as many as 31 civilians were killed and 12 others injured in strikes that hit Al-Hayjah area” in Al-Jawf province. The health ministry in Houthi-controlled Al-Jawf province said women and children were among those killed, Houthi-run Al-Masirah TV reported.
