An Israeli strike killed four ISIS fighters in the Syrian Golan Heights on Sunday, the country’s military said. The strike was called after Israeli troops came under fire in the region. No Israeli solders were injured in the attack. The militants were believed to be members of the Yarmouk Martyrs Brigade, which the U.S. considers to be a terrorist organization and which has pledged allegiance to ISIS. Parts of Golan Heights are controlled by Israel, taken from Syria in 1967. The Israeli soldiers were on their side of the border when they were shot at.
