Russian President Vladimir Putin has skipped his custom of sending season's greetings to countries opposed to his country's military actions in Ukraine, highlighting the confrontation with Western nations.

Russia's presidential office on Friday revealed Putin's Christmas and New Year greetings to foreign heads of state and government.

The heads of countries that received his greetings included former Soviet republics, Middle Eastern and Latin American nations, as well as China and India.

The United States and European countries did not receive his messages this year, except for Hungary and Serbia, as they handle relations with Russia independently.

The Russian government said that last year Putin sent season's greetings to US President Joe Biden, heads of Britain, France and Germany, and Japanese Prime Minister Kishida Fumio.

Kremlin spokesperson Dmitry Peskov made it clear that Putin would not send congratulatory messages to countries not amicable to Russia.

Meanwhile, Russia continued to bomb Ukraine with drones and missiles, targeting its infrastructure in the capital Kyiv and elsewhere on Thursday and Friday.

Kyiv Mayor Vitali Klitschko said although drones were shot down, the falling debris damaged buildings.

The Russian defense ministry said on Friday that its troops conducted large-scale assaults on electricity facilities supporting Ukraine's military command systems and defense industry.
