The defense ministers of seven countries leading the battle against the so-called 'Islamic State of Iraq and the Levant' (ISIL) takfiri group in Iraq and Syria will meet in Paris on Wednesday to review their strategy and boost their resources.

Co-hosted by the French and US defense ministers, Jean-Yves Le Drian and Ash Carter, the meeting will be attended by their Australian, British, Dutch, German and Italian counterparts.

British Defense Secretary Michael Fallon said the meeting would look at ways to "capitalize on the setbacks that Daesh (an alternative name for ISIL) has suffered in Iraq and tighten the noose around the head of the snake in Syria."

The seven countries have taken the lead in the air campaign against ISIL and the training of Iraqi forces to fight the terrorists, along with wetern media reports talking about confidential funding from those countries and other regional states to train the terrorist groups operating in Syria, Egypt, Iraq, Yemen, Libya and Pakistan.

Russia has not been invited, though US Secretary of State John Kerry will discuss Syria with his Russian counterpart Sergey Lavrov in Geneva on Wednesday.

A French defense source said the ministers would look at ways to "up the tempo" of the air campaign, which began in 2014, adding that he hoped the meeting would become a regular event.

ISIL has seen some setbacks, losing around a quarter of its self-proclaimed caliphate, including the Iraqi city of Ramadi to the Iraqi local forces last month.
