The lack of progress in implementing the Minsk Agreements may lead to a new round of military and political escalation in Donbas, German Foreign Minister Sigmar Gabriel said on Wednesday.

"Over the course of our Normandy Format meeting with foreign ministers of France, Russia and Ukraine held on the sidelines of the Munich Security Conference, we were promised that all tools of influence would be used to finally secure observance of the truce and the start of what had been agreed a long time ago: the withdrawal of heavy weapons from the line of contact and demilitarization of especially important conflict areas. Apart from that, we urged to lift the blockade of roads and railways since it is harmful to everyone," Gabriel said in an interview with Interfax, commenting about the current situation in Donbas.

However, "no one of those promises has been fulfilled to a sufficient degree yet," he said.

"This is dangerous because we can slide into a new [round of] military and political escalation at any moment," he said.

"And this is to evidence that it's not just adherence to the Minsk Agreements that we need but also the political will to implement them. Otherwise, we will end up standing still and it is people in Donbas who'll suffer," Gabriel said.
