(Reuters) - Aides to jailed Russian opposition leader Alexei Navalny said on Friday they were seriously worried about his health and had been unable to contact him for three days.

Navalny, 47, is imprisoned in a penal colony east of Moscow and has been sentenced to a total of more 30 years on what he says are trumped-up charges to silence his criticism of President Vladimir Putin.
