Thirteen dangerous criminals who have committed serious criminal offences and crimes against peace and security in the Anti-Terrorist Operation (ATO) zone in eastern Ukraine have been put on Interpol's international wanted list, the media liaison office of the Ukrainian National Police's main department in Donetsk region has reported.

"These are the people being suspected of murder, torture, kidnapping and robbery of citizens are also involved in terrorist groups' activity," the source said.

What is more, a total of 137 cases were handed over to Interpol's General Secretariat in order to put the suspects on the international wanted list in 2015, the Donetsk regional police said. Among them are 27 individuals simultaneously involved in several criminal cases, including crimes against peace and security.

"We closely cooperate with representatives of law enforcement agencies from different countries. Thirteen dangerous criminals, who have committed crimes in occupied territories [in Donbas], have already been put on the wanted list; we have succeeded in proving their involvement in serious crimes despite absence of police's access to those areas. It has been established that simultaneously all these lawbreakers with criminal experience are or were among [Donbas] militants. That is why terrorists and their accomplices, who commit grave crimes, have no chance of hiding beyond Ukraine's borders – we have done everything we could, so that they won't escape the punishment," chief of the Donetsk regional police's main department Vyacheslav Abroskin said.

At present, 85 individuals in total were put on the international wanted list on the Donetsk regional police's initiative. They are subject to detention and extradition. Five persons who have gone missing in other countries were also put on the wanted list at the Donetsk regional police's request. Their whereabouts are to be determined.

Besides, over 300 individuals and 22,500 vehicles were verified with the use of Interpol's databases in Donetsk region within the year.
