No planes will fly to or from Heathrow Airport on Friday after the airport was shut due to a fire at a nearby substation. Passengers have been warned to stay away, with disruption likely to last for days.
Counter-terror police are among agencies investigating the cause of the fire, which is expected to affect more than 1,300 flights today.
Western officials have accused Russia and its proxies of staging dozens of attacks and other incidents across Europe since the invasion of Ukraine three years ago.
They allege that the disruption campaign is an extension of President Putinβs war, intended to sow division in European societies and undermine support for Ukraine β although the Kremlin has denied carrying out sabotage efforts against the West.
Earlier this week, Putin had agreed to a limited ceasefire that stops Russia targeting Ukraineβs energy infrastructure after a phone call with US President Donald Trump.
Now, experts are analysing whether Russia could be linked to the UK substation fire, which is affecting 679 flights scheduled to land and 678 departures from Heathrow.
