One of the climate protesters on hunger strike to demand the German government take more action is in acute danger of dying, according to the campaigners.
After 83 days without eating, 49-year-old Wolfgang Metzeler-Kick is still responsive, but physically very weak, activists from the "Starve until you are honest" campaign announced on Tuesday.
His volunteer medical team has handed over responsibility for his medical care. Nevertheless, he is determined to continue the hunger strike, they said.
Three other men are currently on hunger strike alongside Metzeler-Kick. Two others have ended their strike. The activists are living in a camp set up near the Economy Ministry in Berlin.
They want German Chancellor Olaf Scholz to make a statement on the dangers of climate change and to commit to reducing greenhouse gas emissions.
According to a government spokesman, Scholz does not want to comply with the demands. On Friday, Scholz himself said at a citizens' dialogue: "It is my greatest wish that the action be stopped."
It is a mistake "to use violence against others, but also to use violence against oneself," the chancellor said.
Metzeler-Kick began his hunger strike on March 7. Initially, he did not eat any solid food, but still took juices, electrolytes and vitamins. Since May 24, he has been abstaining from juices in order to intensify his hunger strike.
