BERLIN — Aleksei A. Navalny, the Russian opposition leader who is recovering in Berlin after being poisoned, posted a photograph on Tuesday showing him in the hospital, looking gaunt but very much alive, and telling followers that he was breathing on his own.
“Hello, it’s Navalny,” he said in an Instagram post with a picture of himself sitting up in a hospital bed surrounded by his wife and others. “I can still do almost nothing, but yesterday I could breathe the entire day by myself.”
The message came hours after a senior German security official told The New York Times that Mr. Navalny was awake, alert and had spoken to a German prosecutor but was refusing to cooperate with a Russian inquiry into his case. He also vowed, according to the official, to return to Russia as soon as possible to continue his work.
