The helicopter was a UH-60 medical evacuation helicopter. The incident is under investigation, the Division of Military and Naval Affairs said, adding no further information was immediately available.
New York Gov. Andrew Cuomo said in a statement he was “devastated” by the soldiers’ deaths.
“National Guard members are our citizen soldiers who voluntarily serve and protect both here and abroad, and I extend prayers and condolences from all New Yorkers to the family, loved ones and fellow soldiers of these honorable heroes who we will never forget.”
The governor directed flags on all state buildings to be lowered to half-staff Thursday to honor the victims.
This is a developing story.
