"A question emerges (and not only for us maybe): what is this: powerlessness of the United States or someones conscience line for the prolongation of the conflict? An attempt to play games with the Nusra [Front] militants could lead to the creation of another terrorist monster," the statement read.
The ministry added that the United States was constantly looking for new ways to "give respite" for the terrorist organization.
"Washington agrees that the Nusra Front, which recently changed its name to Jabhat Fatah Al-Sham, is a terrorist organization but refrains from carrying strikes against it."
Earlier in the day, Russian Foreign Ministry's spokeswoman Maria Zakharova said that the United States back in February promised that it would take two weeks to separate the terrorists and the so called moderate opposition.
