Earlier, Sheremetyevo Airport temporarily restricted the arrival and departure of aircraft, with incoming flights diverted to alternate airfields. The airport also evacuated passengers, including those already on board aircraft. The restrictions were later lifted.
Astra later reported that temporary restrictions had also been lifted at Vnukovo and Domodedovo airports.
Moscow came under a large-scale drone attack on the morning of June 18. Mayor Sergei Sobyanin claimed that Russian air defenses had shot down more than 30 drones heading toward the Russian capital.
The attack marked the second strike on the Moscow Oil Refinery in as many days.
On June 16, the facility was targeted by Ukrainian drones. According to Ukraine's Security Service (SBU), the attack damaged the refinery's "heart" — a key primary oil-processing unit.
The Telegram channel Exilenova+ noted that the refinery is protected by dozens, if not hundreds, of air defense systems.
According to Defense Express, the drones passed at least five Pantsir air defense systems deployed on towers or elevated positions.
The Moscow Oil Refinery processes about 11 million metric tons of crude oil annually and supplies roughly 50% of Moscow's diesel fuel needs. Reuters, citing sources, reported that the refinery suspended operations following the drone attack.
