British defence chiefs have said that the Russian military has fired his "super weapon" missile at a key Ukrainian target.
Putin's army has fired its AS-24 KILLJOY ballistic missile into central Ukraine, likely targeting a military airfield.
Experts estimate it is the first use of this missile system in six months.
It comes as frontlines in the conflict in Eastern Europe have been mostly frozen in place due to the Winter.

A Ministry of Defence spokesperson said: "On December 14, 2023, the Russian Air Force highly likely carried out the first use of an AS-24 KILLJOY air-launched ballistic missile since August 2023.
"Russia launched at least one missile into central Ukraine, likely targeting a military airfield."
It comes as Ukrainian officials are waiting on new funding packages from the US and European Union to keep its economy and military machine going.
However, the White House has warned that US aid will run out by the end of the year.

The MOD spokesperson added: "One of the six ‘super weapons’ President Putin announced in 2018, KILLJOY has been ear-marked to play a major role in Russia’s future military doctrine.
"In the Ukraine war, Russia has reserved the weapon for what it perceives as high value, well defended targets.
"KILLJOY has almost certainly had a mixed combat debut.
"Many of its launches have likely missed their intended targets, while Ukraine has also succeeded in intercepting attacks by this supposedly ‘undefeatable’ system."
President Joe Biden is planning one more military aid package in December for Ukraine in its war against Russia
White House national security spokesperson John Kirby said: "When that one’s done ... we will have no more replenishment authority available to us and we’re going to need Congress to act without delay."
Senate Republicans earlier this month blocked an emergency spending bill with $50billion (£40billion) in new aid for Ukraine.
They instead demanded the Biden administration take tougher steps to control immigration at the US-Mexico border.
