The United States accused U.N. Secretary-General Antonio Guterres of "apparently yielding to Russian threats" and not sending officials to Ukraine to inspect drones used by Russia that Washington and others say were supplied by Iran.
Russia has denied its forces used Iranian drones in Ukraine and argues there is no mandate for U.N. officials to travel to Kyiv to investigate the origin of the drones. Iran has acknowledged it had supplied Moscow with drones, but said they were sent before Russia invaded its neighbor in February.
