Prison officials say Ukraine's jailed opposition leader, Yulia Tymoshenko, is being held in a prison cell under 24-hour camera surveillance with the lights permanently on.
Ivan Pervushkin, head of the prison in Kharkiv, told journalists in televised comments on January 3 that "Video surveillance is not forbidden by law."
In order to carry out permanent video monitoring, there has to be sufficient light in the cells," he said.
