British Foreign Minister David Cameron indicated on Saturday that "Britain will take action regarding the death of Russian opposition leader Alexei Navalny during his detention, and it calls on other countries to follow suit." In an interview with Sky News, Cameron stated, "There must be consequences when such horrific human rights violations occur." He added, "What we are doing is looking into whether there are individuals responsible for what happened, and whether there are individual measures we can take." Navalny's spokesperson Kira Yarmysh confirmed his death today, citing an official notification delivered to his mother, Lyudmila. The Russian prison authority stated that "Navalny, aged 47, lost consciousness and died yesterday, after a walk in the penal colony in the Arctic where he was being held."
