Heavy fighting today in the rebel capital city of Donetsk put the ongoing eastern Ukraine ceasefire in serious jeopardy, with both sides claiming the other fired first. The move comes just a day after Ukrainian Premier Arseniy Yatsenyuk talked up the “state of war” between his nation and Russia.

The ceasefire has more or less held since it was brokered by Russia, though it came to the chagrin of NATO, and led to new rounds of sanctions against Russia for “interfering” in the country.

Ukrainian Defense Minister Valery Heletey reported NATO is so eager to see that ceasefire collapse that they’ve started direct shipments of weapons under a sideline deal he claims was made at the Cardiff summit two weeks ago.

“I have no right to disclose any specific country we reached that agreement with,” insisted Heletey. Some NATO nations have denied any plan to provide “lethal aid” to Ukraine’s military, though the alliance did publicly agree to some funding for them.
