The United States yesterday warned Russia of "consequences" if the hunger-striking Kremlin critic Alexei Navalny dies in prison, as the opposition politician's team called for mass protests across Russia to help save his life. A day after Navalny's doctors said Vladimir Putin's most prominent critic could die "any minute", US President Joe Biden's national security advisor said Washington had warned the Kremlin that it would be "held accountable by the international community" if he died. France, Germany and the European Union yesterday joined a growing international chorus of protest at Navalny's plight, and EU foreign ministers will discuss the situation today. Navalny was arrested in January on returning to Russia after recovering from a near-fatal poisoning attack he says was orchestrated by the Kremlin. The Kremlin denies the allegation.
