French Foreign Minister Laurent Fabius accused Russia Tuesday of displaying bravado on the Syria crisis that had yet to be backed up with action against ISIS.

"You have to look at who is doing what. The international community is striking ISIS. France is striking ISIS. The Russians, for the time being, are not at all," Fabius told a news conference in New York.

"If one is against the terrorists, it is not abnormal to strike the terrorists," Fabius added.

His comments come a day after Russian President Vladimir Putin addressed the United Nations General Assembly, calling for a "broad coalition" to fight ISIS in Syria.

Moscow, which does not rule out future strikes against ISIS, recently bolstered its military presence in a regime stronghold in northwestern Syria.

"In essence, what is important in the fight against ISIS is not the media strike but the actual strike. The equation is simple enough: those who are against ISIS are those striking ISIS," Fabius said.

France is part of an anti-ISIS coalition led by the United States in Iraq and Syria. Paris carried out its first strike Sunday, on the eve of the opening of the UN General Assembly.
