Russian opposition leader Alexey Navalny is out of a coma, hospital says

Navalny "is being weaned off mechanical ventilation" and "is responding to verbal stimuli," Berlin's Charite Hospital said. "It remains too early to gauge the potential long-term effects of his severe poisoning," the hospital added.

Navalny, a critic of Russian President Vladimir Putin, became sick from suspected poisoning on a flight to Moscow from the Siberian city of Tomsk last month.

The German government said that tests on Navalny showed "unequivocal evidence" of the use of Novichok, a Soviet-era chemical nerve agent.
