Formula One and the International Luge Federation have also scrapped plans to hold races in Russia.

The FIS decision includes the Ski Cross World Cup competition in Sunny Valley which was set to begin today and end on Sunday (February 27), as well as the aerials competition in Yaroslavl starting tomorrow.

Only Russian skiers took part in ski cross qualification today, as all foreign athletes instead opted to boycott the race and return home.

Women's Ski Jumping World Cup events in Nizhny Tagil and Chaikovsky from March 18 to 20 and March 25 to 27, respectively, and Tyumen's staging of the Cross-Country World Cup finale from March 18 to 20 have also been impacted by the FIS decision.

Athletes are already in Sunny Valley and Yaroslavl for this weekend's contests but the FIS says it is "working closely with the involved stakeholders to ensure their quick return back home."

National governing bodies from Sweden, Norway and the United States had all vowed to boycott FIS World Cups if they were not moved from Russia.

Replacement hosts and dates are set to be confirmed by the FIS in the coming weeks.

Beijing 2022 champions Ryan Regez of Switzerland and Sweden's Sandra Näslund were among the ski cross athletes to pull out of today's competition at Sunny Valley.

The FIS stated that "the safety of all participants and to maintain the integrity of the World Cup" was the reason behind its decision to abandon all World Cup events in Russia.

The FIS Council today confirmed that Russian athletes could continue to participate in FIS competitions under the name and country of Russia, but with the FIS flag and anthem used in official capacities, including ceremonies. 

The World Curling Federation has removed Perm as the host of this year's European Curling Championships in response to the aggression, while the International Federation of Sport Climbing has said it will no longer hold a World Cup in Moscow in April as was planned.

Both events are expected to be moved to alternative hosts.

In luge, Moscow was due to host the final natural track World Cup event of the season, but the International Luge Federation (FIL) cancelled it, citing security concerns.

"The Russian Luge Federation has done a lot of good work in the preparation of the World Cup final in natural track luge in Moscow," FIL President Einars Fogelis said.

"Therefore, it is very regrettable that the 6th FIL World Cup on natural track had to be cancelled. 

"But for us, the safety of the athletes is our top priority at all times. 

"Therefore, after the outbreak of the conflict between Russia and Ukraine, our first goal was to bring all athletes as well as the coaches and officials involved home safely."

The F1 Grand Prix in Sochi, meanwhile, has been removed from the calendar.

The promotion said in a statement that it was "impossible to hold the Russian Grand Prix in the current circumstances".

Four-time champion Sebastian Vettel of Germany had yesterday said he would not take part in the race, should it go ahead, because of Russia's actions in Ukraine.

Jokerit, the Helsinki-based ice hockey team, have withdrawn from the Kontinental Hockey League (KHL) season because of the invasion.

The KHL is largely comprised of Russian teams.

The World Squash Federation also moved its World Junior Championships - set to be played in August - from Saint Petersburg today.
