The US-led military coalition's fight against the Islamic State militant group entered a new phase on Wednesday, with defense ministers from the seven countries most heavily involved in the operation pledging to continue fighting and look for ways to more aggressively target the group.
The United States, France, Germany, Britain, Italy, Australia and the Netherlands made the promise here after a joint meeting hosted by US Defense Secretary Ashton B. Carter and his French counterpart, Defense Minister Jean-Yves Le Drian.
The group said in a joint statement that it has "expressed our broad support for the campaign plan objectives, and the need to continue gathering momentum in our campaign."
Separately, Carter announced during a news conference alongside Le Drian at the French defense ministry that he has invited leaders from all 26 nations involved in the military side of the campaign against the Islamic State, along with Iraq, to meet in three weeks in Brussels in a first-time meeting and detail how they may be able to offer more resources.
That leaves out 37 other countries that are a part of the coalition in some way, but not contributing militarily.
"Every nation must come prepared to discuss further contributions," Carter said of the countries invited to attend the meeting in Brussels.
Le Drian said in the news conference that the United States holds the leadership role in the fight against the Islamic State, but that the French are on the front lines of the battle with about 3,500 service members involved.
Over the last few weeks, the Islamic State has suffered a series of defeats, providing reason to step up operations against the group with a consistent military strategy, he said.
Le Drian added that the cities of Raqqa in Syria and Mosul in Iraq -- de facto capitals of the Islamic State -- must be won back, but that the military coalition also must sever the militant group's control of surrounding areas. The ideology of the group also must be combated, he added, noting the large numbers of people who have traveled to Iraq and Syria from across the world to join the ISIS.
Carter said there is no other defense minister who he has spent as much time discussing the Islamic State fight with than Le Drian, and that they discussed accelerating the campaign against the militants even before the terrorist attacks in and around Paris in November that killed 130 people.
The meeting came after a the arrival of an elite US "expeditionary targeting force" in Iraq that is expected to include up to 200 Special Operations troops. It is not yet clear whether it has begun carrying out operations, but it is expected to conduct raids, collect intelligence and carry out other operations against Islamic State leaders.
As of Jan. 10, the US-led military coalition has carried out 6,341 airstrikes in Iraq and 3,219 in Syria, according to the Pentagon. Of those, the United States has carried out the majority, with 4,361 Iraq and 3,029 in Syria.
The rest of the military coalition has carried out 1,980 strikes in Iraq and 190 in Syria. The countries doing so in Iraq include the United States, Australia, Belgium, Canada, Denmark, France, Jordan, the Netherlands and Britain. In Syria, the nations that have carried out airstrikes include the United States, Australia, Bahrain, Canada, France, Jordan, Saudi Arabia, Turkey, the United Arab Emirates and Britain.
