Observatories operating in the provinces of Hama and Idlib revealed the identity of the commander of the aircraft that carried out the massacre on Khan Sheikhoun in Idlib countryside, which marked the second largest chemical attack in Syria after the August 2013 attacks on both eastern and western Ghoutas in Damascus. Orient Net contacted a number of field, independent and even Syrian Civil Defense observatories in the countryside of Idlib and Hama, and all testimonies indicated that the Assad terrorist who dropped toxic gas-filled barrels on Khan Sheikhoun was colonel pilot, Muhammad Yousef Hasouri. Colonel Hasouri is the commander of the Sukhoi 22 Squadron at al-Sha’yrat airport. His warplane carries Quds 1 banner. He hails from the villages of Talkalakh town from Homs countryside and currently resides with his family in the Assad-controlled al-Sakan al-Shababy neighborhood in Homs city. At approximately 06:30 am on Tuesday (April 4), Colonel Hasouri took off with his Sukhoi 22 and dropped barrels filled with toxic chemicals on the town of Khan Sheikoun in Idlib countryside, killing more than 100 civilians as they slept and injuring more than 400. The majority of those who fell victim to the toxic gas were children. Yesterday’s chemical attack is the largest of its kind since the civilians of eastern Ghouta also suffered from sarin gas attack perpetrated by Assad terrorists on August 2013 which killed more than 1500 civilians. It is worthy to mention that the walky-talkies and wireless connections have become an essential part of the lives of Syrians living in the liberated areas because of their effective role in reporting any sudden assault by Assad or Russian warplanes. In addition, the Syrians use them to announce urgent appeals from hospitals or civil defense stations and report information on the location of the expected Assad or Russian targeting, which contributes to the safety measures and could possibly reduce the number of victims. The observatories operating in the provinces of Hama and Idlib countryside were able to intercept the aviation talks with the operations room of the airport, decipher the code and determine the area the Assad warplane bombed.
