And of course this is being analyzed in order to make the appropriate perfections of this technical equipment," Peskov told journalists.
Peskov declined to specify which type of equipment was found to be faulty citing the "sensitivity" of the subject, but said more detailed information may be received from the Ministry of Defense.
On February 27, a US-Russia brokered ceasefire entered into force in Syria with terrorist groups being excluded from it. Russia also organized a center for Syrian reconciliation at the Hmeimim air base that is a platform for negotiations between the Syrian government and militant groups willing to lay down arms.
