Two Israel Defence Forces soldiers were killed and eight were wounded, half of them seriously, when an Air Force helicopter crashed in the southern Gaza Strip on Tuesday night.
According to a preliminary military probe, the UH-60 Black Hawk had been en route to Rafah with a medical team to evacuate a seriously wounded soldier.
"It appears that the crash was not caused by enemy fire, and the cause is still being investigated," the IDF said.
The names of the soldiers who died will be made public at a later date, added the military.
