Russia has banned all UK airplanes from landing or crossing into its airspace, Reuters first reported on Friday, a day after the British government barred Russian carriers from entering the UK.
Russia's civil aviation regulator announced on Friday morning that any aircraft owned, leased or operated by individuals associated with the UK, or registered there, would not be allowed to enter its airspace.
The move was a response to "unfriendly decisions" made by the UK Aviation Authorities, the Russian regulator said in the announcement.
The UK government banned all Russian airlines – including the country's flag carrier, Aeroflot – from entering its airspace Thursday.
The decision to restrict Russian flights was part of a fresh round of sanctions announced by the UK government Thursday following President Vladimir Putin's decision to invade Ukraine.
"Putin's heinous actions will not be ignored, and we will never tolerate those who put people's lives in danger," Grant Shapps, secretary of state for transport in the UK, tweeted Thursday.
Not long before Russia announced its ban, the owner of British Airways, International Airlines Group, said it was avoiding Russian airspace, CEO Luis Gallego told Reuters.
"We are avoiding Russian airspace for the time being," Gallego told Reuters on Friday. "The impact for us is not huge because right now we are only flying to a small number of destinations in Asia and we can reroute our flights."
A British Airways spokesperson told Insider that the airline has suspended flights to Moscow and would avoid Russian airspace following the announcement of Russia's restrictions.
The latest UK sanctions come on top of moves outlined by London in response to Russia ordering troops into two breakaway regions of Ukraine earlier in the week, which included sanctioning five Russian banks and three individuals.
