Navalny's lawyers say they have not been granted access to him

Lawyers for Alexei Navalny on Monday said they have not been granted access to him since the Kremlin critic was detained on his return to Russia on Sunday, and that his condition was unknown.

Police detained Navalny on arrival in Moscow on Sunday after he flew home from Germany for the first time since he was poisoned last summer, triggering a political clash with the West.
