Ofcom said in a statement Thursday that the Russian broadcaster failed to preserve "due impartiality" in seven programs that aired after the poisoning of former Russian double agent Sergei Skripal.

"The seven breaches represent a serious failure of compliance with our broadcasting rules," the regulator said.
