This is probably what handshake was referring to.......“Vladimir Putin apologized for the fact that the tragic incident occurred in Russian airspace,” the Kremlin said.

The airliner had “repeatedly attempted to land” at the Grozny airport, Putin told Ilham Aliyev, which at the time was being “attacked by Ukrainian combat drones.”

Russian air defense systems “repelled these attacks,” Putin said.

He did not say if the plane was hit by Russian air defenses but the Kremlin said that an investigation was underway and civilian and military specialists were being interrogated.
