This was announced by the deputy head of the mission, Alexander Khug.

The report says that yesterday in just three hours OSCE observers in Yasinovatoy recorded about 500 explosions.

Hug said that last night observers at a newly opened front patrol base in Popasnoy Lugansk region recorded a massive fighting clash.

He stressed that the fighting was so intense in a certain period of time that it was impossible to count the number of explosions.

The report also said that the events in Yasinovataya and Popasnaya might not have happened if the parties had withdrawn heavy weapons, as they promised to do.

Earlier, URA-Inform reported that in the Donbass for a week two civilians died.
