The ambassadors of the G7 countries in Ukraine have aired their concern about Ukrainian captive pilot Nadia Savchenko's health and called on Russia to immediately free her.

"G7 Ambassadors in Ukraine express their serious concerns about the health of Nadia Savchenko, a member of the Ukrainian Parliament and the Ukrainian Armed Forces, who has been imprisoned in Russia since 2014 and is currently on hunger strike in protest against her detention," the ambassadors said in a joint statement posted on the website of the Japanese embassy in Kyiv.

The authors of the statement called on Russia to comply with the Minsk Agreements, including in terms of releasing all hostages.

"G7 Ambassadors call on the Russian authorities to immediately release Nadia Savchenko and to comply with the commitments made in the 'Package of measures for the implementation of the Minsk Agreements' including the release of all hostages and illegally detained persons," the statement says.

As reported, Savchenko has been held in Russian custody since July 2014. She is accused of murder of Russian journalists in the anti-terrorist operation (ATO) zone in Ukraine's east. Savchenko denies all the charges and says that she was brought to the Russian territory by force.

Kyiv and the global community repeatedly called the 'Savchenko case' politically motivated and demanded her release.

The criminal case against Savchenko was tried by the Donetsk City Court in the Russian Rostov region. During a hearing on December 17, 2015, Savchenko went on hunger strike that she intended to continue until the end of her trial. On March 4, she declared a dry hunger strike, refusing to drink water, however, ended it on March 10 before the sentencing, which is scheduled for March 21-22.
