Jailed Kremlin critic Alexei Navalny and a handful of his allies were added on Tuesday to an official list of "terrorists and extremists", the latest in a series of moves by Russian authorities to stamp out their opposition to President Vladimir Putin.
News agencies reported separately that the federal prison service had demanded that Navalny's brother Oleg be given a real jail term in place of a one-year suspended sentence handed to him last year.
