The Russian defense ministry on Wednesday said that seven people died in an attack by Syrian rebels in the city of Aleppo using weapons loaded with a "poisonous agent", AFP reports.
Russian Lieutenant-General Sergei Chvarkov was cited by Russia's TASS news agency as saying that the Nureddin al-Zenki rebel group on Tuesday launched weapons packed with an unnamed "poisonous agent" from an opposition-held neighborhood to a government-controlled area of Aleppo.
