The UN mission will be allowed to enter all the places on Kyiv-controlled territory in Donbas, where it will be possible, Head of the Security Service of Ukraine Vasyl Hrytsak has said.

"We will let the UN mission travel wherever possible," Hrytsak told reporters after a briefing in Kyiv on Monday, responding to a question whether the UN mission will be allowed in Mariupol and Kramatorsk.

He stressed that mutual understanding has been achieved in this issue.

Hrytsak added the mission will be allowed to travel to all areas possible, but in compliance with the norms of Ukrainian legislation.
