"Of course, Moscow has repeatedly stressed that the aid, especially financial or technical, to the opposition in Syria, leads to further destabilization of the situation in the country. This essentially creates a situation which could be used by terrorists from the so-called Islamic State, as the weakened leadership simply loses its potential to stop the growth of the Islamic State," Peskov told reporters.
Since 2013, Washington has been gradually increasing its financial assistance to what it regards as the "moderate" Syrian opposition, while also providing it with small quantities of arms and non-lethal gear. Last month, the United States and Turkey announced a joint plan to provide cover to Syrian rebels from the air to help them seize control of more Syrian territory from ISIL.
US-made military hardware is known to have fallen into the hands of the ISIL militant group. ISIL's influence has been spreading across the Middle East and North Africa as the group continues its fight and local insurgents have sworn allegiance to it.
