The United Nations Security Council met Friday in an emergency session over Russia's attacks on Ukraine's Zaporizhzhia nuclear power plant.

The British representative said this is the first time a state has attacked a functioning nuclear power plant.

Senior U.N. diplomat and Under Secretary-General for Political Affairs Rosemary DiCarlo condemned active military activity near a nuclear site as "not only unacceptable, but highly irresponsible."

"Every action should be taken to avoid a catastrophic nuclear incident," she added, saying an attack on a functioning nuclear power plant is contrary to international humanitarian law.

A new Russian law could send people to prison for up to 15 years for posting "fake news" about the war.

Journalists and media in Russia will now only be able to report what is happening as the Kremlin reports it.

Duma, Russia's legislative body, passed the rule Friday. It will be sent to Russian President Vladimir Putin's desk for it to be signed into law.

The Arctic Council on Friday said it would boycott future talks with Russia over its invasion of Ukraine. Russia currently holds the chairmanship until 2023, according to a report by Reuters.

The intergovernmental forum is designed to promote cooperation between the eight Arctic states of Canada, Denmark, Finland, Iceland, Norway, Russia, Sweden and the U.S.

The council said it is canceling all of its official meetings, including those of its subsidiary bodies, until further notice. Its next meeting was scheduled in Russia this May.

This comes at a sensitive time when climate change is opening up the Arctic to resource exploitation.

The U.S. Commerce Department announced restrictions on certain goods used to refine oil preventing them from going into Russia in response to the invasion of Ukraine.

The restrictions build upon a 2014 rule put in place on the Russian deepwater oil and gas exploration and extraction industries, by denying such items and placing restrictions on a wide variety of items necessary for refining oil.

"These actions will further restrict access to U.S. commodities, software, and technology as part of our ongoing efforts to degrade Russia’s ability to acquire the items it needs to sustain its military aggression," the Commerce Department said in a statement.

The U.S. also added 91 entities to its "Entity List," banning them from use in the U.S. for their involvement in, contributions to or support of Russian security services, military and defense sectors and military and/or defense research and development efforts, the Commerce Department said.

“With each passing day, as Russia continues its assault on Ukraine, it finds itself with fewer places to turn for economic and material support,” said Secretary of Commerce Gina M. Raimondo.

She added, “The United States and our allies and partners will continue to stand strong with the people of Ukraine and today’s actions will further restrict Russia’s access to revenue to support its aggression.”
