Nobel Peace Prize laureate Ales Byalyatski marked his 1,000th day in prison in Belarus on April 9 amid increasing fears about his deteriorating health, his wife said. Natallya Pinchuk told AP that Byalyatski, 61, had been in solitary confinement for the past half-year despite chronic illnesses. She said she had learned from people who have left the prison that his condition is continuing to worsen. She urged the United Nations to "act more actively" to help Byalyatski, who is serving a 10-year sentence linked to his human rights activities, and other political prisoners in Belarus.
