US Secretary of State Mike Pompeo on Thursday urged his Russian counterpart Sergei Lavrov to "immediately release" jailed Ukrainian filmmaker Oleg Sentsov, who has been on hunger strike for more than three months.
Sentsov, a 42-year-old Kremlin opponent, was arrested in Crimea after Moscow's 2014 annexation of the peninsula and has been languishing in a Russian Artic prison with little hope of release.
He announced the hunger strike in May demanding the release of all Ukrainian political prisoners being held in Russia.
Pompeo "noted our concerns about Sentsov's health and urged Russia to immediately release Sentsov and all Ukrainian political prisoners," State Department spokeswoman Heather Nauert said in a readout of the call.
The case has garnered wide international attention.
