STUTTGART, Germany — An international coalition leading the military campaign against the Islamic State in Syria and Iraq agreed Wednesday to accelerate their contributions but did not publicly specify what those would be. The group also called on Iraqi leaders to reconcile political differences.

A day after a U.S. Navy SEAL was killed in small arms fire with IS forces, U.S. Defense Secretary Ash Carter said that as the war intensifies, “these risks will continue.”

Carter identified the SEAL as Navy Petty Officer 1st Class Charles Keating, whose family had confirmed his death on Tuesday. Carter said he regretted the loss but stressed that combat risks in Iraq are unavoidable.

“Our overall approach is to enable local forces to do the fighting … but that doesn’t mean we aren’t going to do any fighting at all,” Carter said. “We are putting these people are risk every day,” including the aircrews who are flying strike missions daily over Iraq and Syria, “and, tragically, losses will occur,” he added.

Other U.S. officials, speaking on condition of anonymity to discuss details not yet publicly released, said that Keating, 31, and his SEAL advisory team were moving between Kurdish Peshmerga units when they got caught in a firefight with Islamic State forces that had created a breach in Peshmerga lines.

Other U.S. officials said Keating was in a group of SEALs who were coming to the aid of a second U.S. military adviser group pinned down by IS fire at or near a Peshmerga command post.

Carter and his counterparts from 11 coalition countries met behind closed doors at the headquarters of U.S. European Command, where Carter was presiding at a change-of-command ceremony Tuesday when news of Keating’s death reached him.

In a joint statement issued after the meeting, the group reaffirmed its support “to further accelerate and reinforce the success of our partners on the ground and for the deployment of additional enabling capabilities in the near term.”

“We called on all of Iraq’s political leaders to commit themselves to the legal and peaceful reconciliation of political differences in order to confront the nation’s challenges and to remain united against the common enemy,” they said.
