Ukraine’s air force has shot down one of its own drones which it says had lost control above central Kyiv. There were explosions for around 15 to 20 minutes on Thursday evening as air defence attempted to shoot it down in an area near the president’s office. Ukraine presidential chief of staff Andriy Yermak initially said it was an enemy drone that had been shot down. But the air force later admitted it was Ukrainian and had been destroyed to avoid “undesirable circumstances”. Videos of efforts to shoot down the drone had been shared widely on social media. Cheers could be heard when the drone was finally taken down.
