JERUSALEM (JTA) — Israeli Air Force jets were scrambled to the north and south of the country in pursuit of unidentified aircraft that entered Israeli airspace.

The Israel Defense Forces would not comment on Saturday’s incident, which involved three IAF jets in pursuit. It is believed that the military suspected unmanned drones had infiltrated Israel’s airspace.

A week earlier, IAF jets were scrambled to intercept what was believed to be a drone but turned out to be a flock of birds.

Israel’s military has intercepted two drones in the past 12 months that were believed to have been sent from Hezbollah in Lebanon.
