MOSCOW, July 8. /TASS/. Terrorists have cobbled together at least 15 improvised explosive devices packed unknown substances in order to stage false flag attacks in Syrian inhabited localities, Alexander Shcherbitsky, chief of the Russian Center for Reconciliation of the Opposing Parties in Syria, said on Wednesday.
