Russia has accused Ukraine of attempting to use drones to assassinate Vladimir Putin. Overnight on Tuesday, two drones were spotted above the Kremlin. In footage shared on social media, one of them appeared to explode in the air near the dome of the residential area of the capitol building. 

In the aftermath, Moscow said it was able to disable the drones, and blamed Kyiv for the attack. Ukraine denied any role in the incident and suggested Russia is planning its own terrorist acts.
