Russian President Vladimir Putin’s spokesman said Friday that Ukraine’s offensive against pro-Moscow rebels in the east dealt a final blow to a faltering peace deal aimed at easing the crisis in the ex-Soviet country.

“While Russia is making efforts to de-escalate and settle the conflict, the Kiev regime moved combat air forces against peaceful settlements, began a reprisal raid, essentially finishing off the last hope for the feasibility of the Geneva accords,” Dmitry Peskov was quoted as saying by Russian news agencies.
