The Russian Ministry of Defense (MoD) says the Al-Nusra Front terrorist group has deployed chemical weapons near Syria’s city of Aleppo.

Scores of militants have also arrived from Turkey in the outskirts of the city in order to participate in the clashes there.

“Several trucks carrying self-made ammunition, armed with chlorine-based toxic agents, have arrived from the Idlib province to the northern outskirts of the city of Aleppo controlled by al-Nusra Front terrorists,” the MoD’s daily bulletin reads.

On May 12, the violence escalated in the Aleppo province as the ceasefire expired.
