As many as 137 Ukrainian citizens are being held captive in Donbas territories not controlled by Kyiv, says Iryna Gerashchenko, a Ukrainian representative in the humanitarian subgroup in the Trilateral Contact Group for settling the conflict in Donbas.

Ukrainian President Petro Poroshenko has had a meeting with the members of the humanitarian subgroup, the Petro Poroshenko Bloc party press service reported on Friday.

"Based on the Ukrainian Security Service information, 137 people are being held hostage today. We are ready for compromises in exchange for their liberation. We have already made several proposals. The key of these is the liberation of 25 Ukrainians who are severely injured and women. We are also prepared to consider other options and are working to be able to report good news in the near future. But the Ukrainian side tries not to make announcements but to talk about events that have already happened," the Petro Poroshenko Bloc press service quoted Gerashchenko as saying.

Kyiv also stands ready to free its captured opponents who did not commit grave crimes, she said.
