  • Russia's heavy bomber aircraft haven't fired cruise missiles at Ukraine in more than a month, UK intel said.
  • The UK MOD said that's "one of the longest gaps in such strikes since the conflict began."
  • Russia needs to reduce its strike frequency to replenish its supply of missiles, it said.

Russia's fleet of heavy bomber aircraft have not fired cruise missiles at Ukraine in more than a month, according to UK intelligence.

The reason, UK Ministry of Defence said, was Russia having too few missiles, leading them to save them for later.
