Russia has declined to comment on US claims that Iran could supply it with ballistic missiles. Ukraine said it shot down a "rare" Iran-built drone amid a barrage of attacks overnight. The Ukrainian Air Force said on Wednesday that it had downed more than a dozen attack drones and a cruise missile. The overnight assault followed a report by authorities in the southern region of Odesa that a rare Iranian-designed attack and reconnaissance drone had been destroyed. The air force said the overnight barrage was launched from southeast Russia and that a combination of air defence units in several central regions had "destroyed all 14 enemy Shahed-131/136 drones".
