MOSCOW (Sputnik) — The adviser to the Supreme Leader also urged US-supporters to learn a lesson from the US airstrikes.
"[Such actions unveil] real goals masked by the truce plan," Haddad Adel told Fars News Agency.
"Those who remain optimistic about the Americans and trust them, should learn a lesson from this aggression. The Americans would never refuse to break the promises," Adel added.
On September 9, Russian Foreign Minister Sergey Lavrov and US Secretary of State John Kerry announced a new peace plan to address the five-year conflict in Syria. The ceasefire stipulated by the agreement came into force on September 12. Humanitarian access, along with seven days of reduced violence, are some of the conditions of the US-Russia deal.
