Israel strikes targets in Syria after missile attack at its nuclear facility

A missile launched from Syria was fired into southern Israel early Thursday, setting off air raid sirens near the country’s top-secret nuclear reactor, the Israeli military said. In response, it said it attacked the missile launcher and air-defense systems in neighboring Syria.

The incident, marking the most serious violence between Israel and Syria in years, pointed to likely Iranian involvement. Iran, which maintains troops and proxies in Syria, has accused Israel of a series of attacks on its nuclear facilities, including sabotage at its Natanz nuclear facility on April 11, and vowed revenge. It also threatened to complicate U.S.-led attempts to revive the international nuclear deal with Iran.
