The Security Service of Ukraine conducted a large-scale operation targeting four Russian military airfields on Sunday, an SBU source confirmed.

A major operation has been launched by Ukraine using drones to destroy Russian strategic bomber planes, according to the Ukrainian security service.

Ukraine has carried out large-scale drone strikes against four airbases deep inside Russia, destroying multiple combat planes, according to a source in the Ukrainian Security Service (SBU).

Russian President Vladimir Putin signed a decree that forces Ukrainians to legalize their status in occupied territories — or leave. Already, many Ukrainians had been forced to accept Russian citizenship in occupied areas to maintain their homes or access to health care and education.

By making harsh, uncompromising demands in peace talks with Ukraine while continuing to pummel it with waves of missiles and drones, Russian President Vladimir Putin is sending a clear message: He will only accept a settlement on his terms and will keep fighting until they’re met.
