- Russia claimed Wednesday that Ukraine tried to assassinate Putin with a drone attack at the Kremlin.
- Experts say there are some things that "don't quite add up."

Security cameras captured striking footage of two drones, one of which can be seen exploding on video, above the hardened Kremlin citadel this week.
Russian officials claimed the overnight drone incident was an attempt by Kyiv to assassinate its leader, but with little evidence linking it to the drones. Ukraine says it wasn't them. So who was responsible?
