Novaya Gazeta, which Al Jazeera English describes as Russia's most prominent investigative newspaper, is closing, the outlet reported. Staff of the newspaper accuse the Russian government of killing the publication off, according to the same report. The report's headline links the reported closure to murders, arrests and pressure. It is not yet clear when the closure takes effect, which government actions staff blame, what the murders, arrests and pressure involved, or whether the Russian government has responded.
