(JNS.org) An Israeli civilian was killed in a shooting incident along Israel’s border fence with Egypt Tuesday afternoon.

The civilian, who was carrying out maintenance work for the Defense Ministry, was airlifted from the scene but was later pronounced dead upon arriving at the Soroka Medical Center in Beersheva, the Jerusalem Post reported.

The Israel Defense Forces said it was investigating the shooting. The source of the gunfire was not immediately clear.

The Egyptian military has been carrying out large-scale operations against Islamic State-affiliated terrorist groups in the Sinai Peninsula recently. On Sunday, the Egyptians killed an estimated 70 terrorists in operations in northern Sinai.
