Earlier in the day, Russia's upper house of parliament unanimously approved the use of Russian armed forces to fight Islamic State (ISIL) jihadist group's targets in Syria. The decision followed a request for assistance from Syrian President Bashar Assad and concerns only Russian warplanes.
"[Russian President Vladimir] Putin needs a sort of agreement with [US President Barack] Obama for security reasons, so that planes do not collide in midair. And some planning of the mission with, perhaps, flight zones," Dhuicq said.
Earlier in the day, a US defense official told Sputnik that the United States would not modify its military operations in Syria regardless of Moscow’s "demarche" of starting its own air operations against ISIL.
Since 2014, a US-led coalition, comprising over 60 states, has been conducting airstrikes against ISIL positions in Syria, without the approval of Damascus or the UN Security Council.
