PARIS (AFP) - French warplanes carried out a second wave of strikes overnight on Islamic State in Iraq and Syria (ISIS) targets in Syria, Defence Minister Jean-Yves Le Drian said on Friday (Oct 9).

"Two Rafale jets dropped bombs on an IS training camp. The objectives were accomplished," he told Europe 1 radio, referring to the other name for the ISIS militant group.

He added that further air strikes would follow.

Le Drian also said "80 to 90 per cent" of Russian strikes in Syria were aimed at propping up President Bashar al-Assad, Moscow's long-term ally.

"The Russian military action in Syria over the past 10 days does not target Daesh, their main aim is (to ensure) the security of Bashar al-Assad," he said.

French President Francois Hollande said this week that failure to act in Syria risks stoking a "total war" in the Middle East.

France carried out it first air strikes in Syria on September 27.
