The Israeli military stated that it was a false alarm that triggered missile sirens in the Golan Heights. Earlier, locals reported hearing explosions at the time of the alert.
The IDF spokesman said that an investigation was underway and warned that "the reports regarding an aircraft that was identified and intercepted are false."
Following reports regarding sirens in the Golan Regional Council, it appears to have been a false alarm. The IDF's Iron Dome aerial defense system was activated. The circumstances are being looked into— IDF (@IDFSpokesperson) May 17, 2018

Tensions on the border have been running high recently, with the latest incident occurring on May 10 when Iranian forces in Syria launched missiles at Israel which were intercepted by the Iron Dome, according to Tel Aviv. It prompted Israel to attack Iranian targets in Syria in what became the most intensive strike into Syria since the start of the civil war in the country.
Following reports in the media that Iran was preparing a response to April's alleged Israeli attacks on Iranian facilities in Syria, the IDF announced its defense systems were "on high alert for an attack," due to what it said was "irregular activity of Iranian forces in Syria."
