The working group on security has drafted two documents regarding the weaponry removal in Donbas, which reflect suggestions made by both sides in the conflict, a source in the Trilateral Contact Group told Interfax on Monday.

"At its meeting in Minsk on August 4 the working group on security drew up a document in two versions. These set out all the debatable aspects and take into account the positions of both sides in the conflict," the source said.

Both versions will be submitted for consideration by the Contact Group as soon as its members get together, he added.

The source has not ruled out that the Contact Group could meet before the scheduled date. It was reported earlier that the Contact Group could hold its next meeting in Minsk on August 26.
