JERUSALEM (CNN) -- The Israeli air force shot down a drone approaching the nation's coast Thursday, the Israel Defense Forces said.
An Israeli aircraft shot the drone down five nautical miles off the coast of Haifa. Israeli naval forces were searching the area and an investigation is under way.
Thursday's incident marked the second time an unmanned aircraft had been intercepted in Israeli airspace within the past seven months, the IDF said.
In October 2012, Israeli warplanes tracked and eventually shot down a drone over the country's northern Negev Desert.
That drone did not carry any weapons or explosives, Israeli officials said at the time. They declined to discuss the drone's route or whether it had approached any sensitive facilities.
Hezbollah claimed credit for sending the drone, which Israeli officials at the time said appeared to have originated in Lebanon.
Hezbollah frequently flies drones over Israel, but the military rarely bothers to shoot them down, Micha Zenko of the Council on Foreign Relations said at the time.
