Israel has launched its most ferocious attack inside Syria, since the war of October 1973. But now the target is Iran, Syrian President Bashar Al Assad's ally.
Just a day after the Trump administration walked out of the Iran nuclear deal, Israel accused Iran of firing rockets on the Golan Heights, which Israel occupies. Tehran says those claims are baseless.
Israel responded by striking dozens of Iranian positions in Syria.
The two sides have exchanged hostile rhetoric for years, but now there are signs of an open military conflict, putting the region on edge.
