A Syrian Arab Army unit on Tuesday uncovered a warehouse containing toxic chemicals which terrorists had used to make shells inside a school in Hanano area in Aleppo.

SANA’s correspondent said that while army engineering units were searching for landmines and IEDs and dismantling them in the areas to which security and stability have been restored, they uncovered a large warehouse set up by terrorists inside Sana’a Mhaidali School in Hanano area, finding large amounts of highly-toxic chemicals inside it which terrorists had been using to make shells containing toxic materials.

The correspondent also said that the warehouse contained explosives and equipment used for manufacturing rocket shells and weaponized gas cylinders.

Back in November, terrorists fired mortar shells containing chlorine gas on al-Nairab area and Manian village, causing dozens of cases of asphyxiation, and before that terrorists had fired shells containing toxic gasses on residential neighborhoods multiple times, including on October 31st when they targeted al-Hamadaniya neighborhood and al-Assad Suburb with shells containing gases, causing 48 cases of asphyxiation.
