Tel Aviv - An Israeli F-16 fighter jet has crashed amid Syrian anti-aircraft fire after an offensive against Iranian targets in Syria, the Israeli military says.
The two pilots parachuted to safety before the crash in northern Israel. It is believed to be the first time Israel has lost a jet in the Syrian conflict.
Israel was carrying out strikes after the launch of an Iranian drone into Israel. The drone was intercepted.
Syria accused Israel of "aggression", as Israel then launched more strikes.
Israel Defense Forces (IDF) tweeted: "Moments ago, IAF aircraft, targeted the Syrian Aerial Defense System & Iranian targets in Syria. 12 targets, including 3 aerial defense batteries & 4 Iranian military targets, were attacked. Anti-aircraft missiles were fired towards Israel, triggering alarms in northern Israel."
Israeli strikes in Syria are not unusual, correspondents say, but the loss of an Israeli fighter jet marks a serious escalation.
In a statement, the Israeli military said "a combat helicopter successfully intercepted an Iranian UAV [unmanned aerial vehicle] that was launched from Syria and infiltrated Israel".
It said the drone was identified quickly and was "under surveillance until the interception".
The drone went down on Israeli territory and was "in our possession", IDF spokesperson Brig Gen Ronen Manelis said.
The military said that in response the IDF "targeted Iranian targets in Syria". It said the mission deep inside Syrian territory was successfully completed.
After coming under Syrian anti-aircraft fire, the F-16's two crew ejected and were later taken to hospital. One of them was "severely injured as a result of an emergency evacuation", the IDF said.
It was not clear whether the F-16 jet was hit by anti-aircraft fire or went down near Harduf for other reasons.
It is the first time Israel has lost an aircraft in combat since 2006 when an Israeli helicopter was shot down over Lebanon by a Hezbollah rocket, the Jerusalem Post reports.
