German doctors have been allowed to visit Ukrainian military pilot Nadiya Savchenko, who has been on hunger strike for more than two months in a Russian jail, a German Foreign Ministry spokesman said on Monday.
Savchenko, 33, was captured by pro-Russian forces and handed over eight months ago to Russia, where she was imprisoned on charges of aiding the killing of two Russian journalists in east Ukraine. At home, she has become a symbol of resistance to Russian aggression.
German Foreign Minister Frank-Walter Steinmeier asked Russian President Vladimir Putin to allow the humanitarian visit during talks on a cease-fire for eastern Ukraine in Minsk on February 11-12, spokesman Martin Schaefer said.
Two German doctors visited her on Feb. 15, then held talks with her prison doctors, in which Savchenko was included.
Savchenko is reported to have lost 17 kilograms (37 pounds) since going on a water and glucose diet in December.
Schaefer told a regular government news conference that Germany was extremely concerned about her health, and repeated an appeal for her release.
He gave no further details of her condition, and said it was regrettable that reports had appeared in Russian media despite an agreement to maintain confidentiality.
Russia's Investigative Committee said the pilot provided the coordinates of two Russian journalists who were killed by a mortar attack in June in the Luhansk region of east Ukraine, held by pro-Russian rebels. She denies the accusation, but could be jailed for up to 20 years if found guilty.
Steinmeier is a member of the traditionally Russia-friendly Social Democrats (SPD) and has long ties with Putin, although he has stuck closely to Chancellor Angela Merkel's tough line with Moscow over its backing of separatists in east Ukraine.
