MOSCOW (Reuters) - Jailed Kremlin critic Alexei Navalny said in statement passed to his lawyers on Thursday that he was being prevented from sleeping by prison guards, a practice he likened to torture.

He also said he had asked prison authorities to let a civilian doctor visit him in jail because of serious pain he was experiencing, but said he had been refused.

One of his lawyers said earlier on Thursday that Navalny had been experiencing health problems for several weeks in jail.
