Seven US service members were killed Thursday in a helicopter crash in western Iraq, the US military said.
Army Brig. Gen. Jonathan P. Braga, the director of operations for the combined task force leading the fight against ISIS in the region, said all personnel aboard the HH-60 Pave Hawk helicopter were killed.
New York Mayor Bill de Blasio announced Friday that two members of the New York Fire Department were among those killed in the crash.
The names of those aboard the helicopter were not immediately released pending the notification of next of kin.
However, it was later announced that Lt. Christopher J. Raguso and Christopher T. "Tripp" Zanetis were the two NYFD members killed.
"They are truly two of New York City's bravest -- running into danger to protect and defend others, both in New York City and in combat overseas," de Blasio said. "On behalf of all New Yorkers, I extend my deepest condolences to their families, loved ones, and fellow service members and FDNY members."
The military said the crash, which is under investigation, "does not appear to be a result of enemy activity."
President Donald Trump offered his condolences to the families Friday morning.
"Their sacrifice in service to our country will never be forgotten," the President tweeted.
