The Ukrainian side views the attacks on the checkpoints on the dividing line between the parties to the conflict in Donbas inadmissible, Ukrainian representative in the Trilateral Contact Group's humanitarian subgroup, Verkhovna Rada Deputy Speaker, Iryna Gerashchenko, said.

"Ukraine's position is that ahead of the major holidays, the number of people who want to visit relatives or the native towns, is on the rise these days. The attacks on the checkpoints are inadmissible, which resulted in the damage to the checkpoints in Stanytsia Luhanska and now the facilities need a repair there," Gerashchenko wrote on her Facebook page on Wednesday.

Gerashchenko recalled that, as of now, the checkpoints do not operate in the Luhansk region due to security issues.

"And, therefore, one needs to urgently stop the violation of ceasefire on the contact line, specifically at the places of checkpoints and negotiated transport corridors. We call for the checkpoints to work quicker, and people to be able to visit their relatives on holidays," she said.

The sides focused on the operation of the checkpoints at a meeting of the humanitarian subgroup in Minsk, Gerashchenko said.

The access of international humanitarian organizations to the occupied territories has also been discussed at the meeting, she said. Additionally, the Ukrainian side suggested the issues concerning the observance of the rights of children in the conflict area be discussed at one of the next meetings of the group.

The participants in the negotiating process on Ukraine call on the warring parties in Donbas to resume the operation of the checkpoints on the contact line shortly, Organization for Security and Co-operation in Europe (OSCE) Special Envoy Martin Sajdik said, previously on Wednesday.
