"The parties have tentatively achieved progress in approving draft documents. The probability of them being signed at the next meeting of the contact group on March 2 is high," the source said. The source said the documents govern procedures governing mine clearance, the security of checkpoints, and also a ban on training near the contact line. A source in one of the subgroups told Interfax that no documents were signed at the contact group meeting in Minsk on Wednesday. OSCE Special Representative Martin Sajdik told reporters on Wednesday that the subgroup on security issues will continue working even after the contact group meeting. Denis Pushilin, envoy from the self-proclaimed Donetsk People's Republic (DPR), said earlier that a document banning military trainings within thirty kilometers of the contact line was being prepared to be signed in Minsk on February 24.
