Russia restricts Estonian border zone; Ukraine hits refineries, drone site

Russia imposes restrictions near the Estonian border amid mobilization concerns, while Ukraine confirms strikes on two oil refineries in Ufa and Samara and a drone storage/launch site in Oryol Oblast, damaging five launchers. The SBU also claims it foiled an FSB-linked plot to assassinate a kickboxing federation president in Kyiv. These actions indicate continued escalation in cross-border strikes and internal security operations, with no sign of de-escalation.
