The Ukrainian Foreign Ministry published a strongly-worded statement on Facebook, calling the detention of the mayor of Melitopol by armed men a "war crime."
CNN has previously reported that the Melitopol mayor, Ivan Fedorov, was seen on video being led away from a government building in the city by armed men. A short time later, the Russian-backed Luhansk regional prosecutor claimed Fedorov had committed terrorism offenses and was under investigation.
In a statement posted on Facebook, the Ukrainian Foreign Ministry called Fedorov's detention an "abduction," saying it is one of the many "gross violations of norms and principles of international law, including international humanitarian law, war crimes and crimes against humanity, as well as other human rights violations by the Russian military."
The Foreign Ministry said that the Geneva Convention and its Additional Protocols prohibit civilian hostages like Fedorov from being taken.
"We call on the international community to respond immediately to the abduction of Ivan Fedorov and other civilians, and to increase pressure on Russia to end its barbaric war against the Ukrainian people," the statement said.
"The fact of the abduction of the Mayor of Melitopol, along with hundreds of other facts of war crimes by Russian occupiers on the Ukrainian soil, are being carefully documented by law enforcement agencies. The perpetrators of this and other crimes will be brought to the strictest responsibility," the post concluded.
