On February 28, the White Helmets asserted that the Syrian regime and Russia used Tochka missiles to target an area east of Aleppo. Video posted online on March 6 showed the wreckage of a Tochka missile allegedly used in the March 5 attack on the oil facilities.
Video from March 5 showed the strikes and the aftermath as well as missile fragments that were found. Social media accounts asserted that the Tochka missile fragments found near Tarhine in Syria indicate Russia was behind the attack. Others said it was the Syrian regime. Such a large attack would likely not happen without both being aware of it, regardless of which forces fired the missiles. Some said the missile were fired from the Kuweireis air base which is 30km east of Aleppo.
