“Explosives-laden cars and rockets equipped with toxic agents are being prepared by Nusra Front militants for an attack on the residential areas of the city of Aleppo in northern Syria,” the head of the Syrian Human Rights Network Ahmad Kazem said, Sputnik reported.
"Al Nusra terrorists prepare car bombs filled with chlorine, white phosphorus and phosphates as well as Grad and Elephant rockets equipped with poisonous substances for attacks on residential areas of the city of Aleppo," Kazem added.
According to human rights activists, the terrorists plan to use poisonous substances in the areas to accuse the Syrian army of chemical attack.
Earlier in May, the US State Department of State said Washington was collecting information regarding a chemical weapons attack in Syria that had allegedly been carried out by the Syrian government.
The Russian Defence Ministry said that Al Nusra militants were preparing to stage a provocation in Syria's Idlib province in order to thereafter accuse the Russian forces and the Syrian army of allegedly attacking civilians with chemical weapons.
