Apple announced on Tuesday it has paused all product sales in Russia in response to the Russian invasion of Ukraine.

"We are deeply concerned about the Russian invasion of Ukraine and stand with all of the people who are suffering as a result of the violence," Apple said in a statement quoted by Reuters.

"We are supporting humanitarian efforts, providing aid for the unfolding refugee crisis, and doing all we can to support our teams in the region," the company added.

Apple outlined a number of actions in response to the invasion, including stopping all exports into its sales channels in the country. Apple Pay and other services have been limited, the company said. The Russian state media, RT News and Sputnik News, are no longer available for download from the Apple Store outside Russia.

Russia has been hit by a slew of sanctions since its invasion of Ukraine last week. Last week, EU leaders agreed to impose new economic sanctions on Russia, freezing Russian assets in the bloc and halting its banks' access to European financial markets.

A day later, the EU announced a freeze on the assets of Putin himself, as well as on his Foreign Minister Sergei Lavrov.

World leaders also decided to cut off Russian financial institutions from using the SWIFT money transfer system.

On Monday, the EU added top Kremlin-linked oligarchs to its sanctions blacklist as part of its latest round of punishment over the Ukraine invasion.
