Police detained more than 1,000 people at protests across Russia in support of jailed Kremlin critic Alexei Navalny on Wednesday, the OVD-Info protest monitoring group said. The AFP reports that supporters of President Vladimir Putin’s most prominent opponent fear he soon could die in prison, where he is on hunger strike, and are demanding he is given proper medical care. Officials say he has been treated like any other convict would be and have warned the rallies are illegal. Navalny’s team called the unsanctioned demonstrations after reports that his health is deteriorating while on a hunger strike, which he began on March 31.
