Putin critic Navalny detained on return to Russia 5 months after being poisoned

Russian opposition leader and critic of President Vladimir Putin, Alexey Navalny, was detained by police on Sunday, moments after his return to the country and five months after he was poisoned with the nerve agent Novichok. The 44-year-old was placed on the country's federal wanted list last month for violating terms of probation related to a years-old fraud case.
