Russia has claimed it stopped two drone attacks on Vladimir Putin’s presidential home overnight.
The Kremlin blamed Ukraine for what it called a “terrorist act”.
It said Russian military and security forces disabled the drones before they could strike.
No victims or damage were reported and Mr Putin was not injured, it added.

“As a result of timely actions taken by the military and special services with the use of radar warfare systems, the vehicles were disabled.”
Footage on Russian social media appears to show a plume of smoke rising over the Kremlin following the alleged attack.
Sky News has been unable to independently verify the footage.
Kremlin spokesman Dmitry Peskov told Russian state news agency RIA Novosti that Mr Putin was not in the Kremlin at the time and was working in Novo-Ogaryovo, outside of Moscow.
The Kremlin added that Mr Putin’s schedule was unchanged.
There was no immediate comment from Ukraine.
Military analyst Sean Bell told Sky News that while Ukraine has been doing “a lot of activity with drones”, it “does feel odd that Ukraine would be so audacious as to mount something in Moscow”.
