Navalny allies detained at Moscow airport, says aide

Russian police on Sunday detained four top allies of Kremlin critic Alexei Navalny at a Moscow airport where they were to meet him on his return from Germany, a senior associate said.

Ivan Zhdanov, the head of Navalny's Anti-Corruption Foundation, said on Twitter that key ally Lyubov Sobol was among the four detained. Footage shot by local journalists showed police leading her and the others away.
