Israel carried out an air strike in Syria on Monday, killing four Islamic State militants.
The overnight air strike in the Golan Heights targeted an abandoned United Nations building that Israel said was used as a base by the militants, reported The Associated Press.
In a clash on Sunday, militants affiliated with the IS group opened fire at an Israeli patrol on the Israeli side of the Golan Heights.
Israeli aircraft responded, killing four militants in an air strike on a machine gun-mounted vehicle.
No Israeli troops were hurt, but it was a rare attempt by IS-affiliated militants to ambush Israeli forces.
