Confidants report disappearance of imprisoned Russian war opponent Kara. He is considered a sharp critic of Putin, survived poison attacks and is currently serving the highest sentence ever received by an opposition figure in Russia.

The prison system has not announced which camp Kara-Mursa is now being held in. The opposition figure is considered one of the harshest critics of Kremlin leader Vladimir Putin and is internationally classified as a political prisoner.. In December, for example, there was no sign of life from opposition activist Alexei Navalny, who until then had been imprisoned in a camp not far from Moscow.
