The Russian Grand Prix scheduled for September 25 has been cancelled in the wake of Russia's invasion of Ukraine, the sport's owners Formula One announced Friday.
F1 were reacting to Russian President Vladimir Putin defying Western warnings to unleash a full-scale invasion Thursday that quickly claimed dozens of lives and displaced at least 100,000 people.
Fighting has gone into a second day with Ukrainian forces fighting off Russian invaders in the streets of the capital Kyiv.
Their rapid action over the race comes after defending world champion Max Verstappen and four-time champion Sebastian Vettel had publicly declared at testing in Barcelona their opposition to driving in the race.
American Formula 1 team Haas, which have a Russian driver Nikita Mazepin, showed their distaste for the invasion by announcing their cars will not sport the Russian colors of its title sponsor Uralkali during the last day of pre-season testing Friday.
Haas whose cars usually sport the blue, white and red colors of the Russian flag, "will present its VF-22 in a plain white livery, without the Uralkali branding, for the third and final day of testing" in Catalonia, the team said in a statement.
Team principal Guenther Steiner, who maintained that the team was "financially OK", said a decision would be announced next week on the future of Haas' long-term collaboration with Uralkali.
The future of Mazepin, whose father Dmitry Mazepin is the non-executive director of Uralkali and close ally of Russian President Vladimir Putin, is also in question.
Steiner acknowledges that the 22-year old's career with the team "must be resolved" but said "it's not all up to us".
Mazepin, who was due to drive during Friday's morning session, made no comment on the war in Ukraine in a tweet he made to his "fans and followers" Friday.
This was due to be the last Russian Grand Prix in Sochi which has hosted the race since 2014.
Next year it is due to move to Saint Petersburg.
