The video brought back the haunting images of the August 21 Ghouta massacre from last year that killed at least 281 to 1,729 people, including civilians and rebel fighters.
While the rebels and the Syrian government blamed each other for the purported chemical attack, President Bashar al Assad released a statement claiming the three-year-old civil war is turning in his regime’s favor.
"This is a turning point in the crisis, both militarily in terms of the army's achievements in the war against terror, and socially in terms of national reconciliation processes and growing awareness of the truth behind the (attacks) targeting the country," Syrian state news agency (SANA) quoted him as saying.
Over the past few years, the demonstrations and protests against tyrannical governments in the Middle East brought about some of the most important changes in the region itself and world politics as a whole.
Long-time dictators were brought down in Libya, Tunisia, Egypt, Lebanon and Yemen while civil unrest is still ongoing in countries like Bahrain, Kuwait, Algeria and Jordan.
But the only Arab state where the mass protests against the government escalated into civil war was Syria, which over the course of three years, turned into what some have called the worst humanitarian crisis in modern times.
Following the Ghouta attack, the United States considered a military intervention against Assad.
However, owing to its Russian ally President Vladimir Putin, the Syrian government was forced to surrender its chemical weapons.
According to a deal that was struck last year in September, Assad agreed to abandon a chemical arsenal that was allegedly responsible for the August 2013 massacre.
