“The US and its regional allies lack the necessary sincerity and seriousness in their fight against the ISIL,” Chairman of the Iranian Parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi said during a meeting with the former French prime minister, Dominique de Villepin, in Tehran on Wednesday.

“By supporting acts of terrorism in Syria duting the past four years, the US and its allies in the region have paved the way for the emergence of the status quo” in the Middle East, said Boroujerdi.

On September 22, the US, Bahrain, Qatar, Saudi Arabia, Jordan and the United Arab Emirates began launching airstrikes on the ISIL targets in Syria.

Using a mix of manned aircraft - fighter jets and bombers - plus Tomahawk cruise missiles, the strikes were part of the expanded military campaign that US President Barack Obama authorized earlier in order to disrupt and destroy the ISIL militants.

During the meeting, the former French premier, for his part, expressed deep concern over acts of terrorism in the region by the ISIL militants.

He also described Iran’s role in restoring peace and stability to the Middle East region as significant, saying that without considering the country's role, regional crises cannot be resolved.
