More than 2,000 people including well-known artists, politicians and intellectuals from different countries have signed an open letter to European leaders, which contains the call to help the release of Ukrainian pilot and MP Nadia Savchenko, who was kidnapped and has been imprisoned in Russia for over 20 months.

"We appeal to you to take emergency measures with the goal of the immediate and unconditional release of 34-year-old Nadia Savchenko, a Ukrainian citizen, kidnapped and imprisoned for more than twenty months in the Russian Federation," the letter reads.

The document says that the Russian authorities "have made a mockery of civil rights, international law, and their own Constitution." They show disdain for the international community and the Minsk agreements.

"So far, all efforts of the international community have proven unsuccessful. On March 4, in protest against the proceedings of the Russian court, Nadia Savchenko announced a full hunger strike, refusing even liquids. Our ability to save her life will test the effectiveness of international diplomacy and our commitment to European values," the petition says.
