Police detain Kremlin critic Navalny on arrival in Russia

Police detained top Kremlin critic Alexei Navalny on Sunday when he flew back to Russia months after barely surviving a poisoning attack, prompting a new wave of Western condemnation. Navalny was detained at Moscow's Sheremetyevo airport less than an hour after he flew in from Germany, where he had been recovering from nerve agent poisoning which he says was ordered by Putin.
