The Israel Defense Forces says it shot down a drone that infiltrated Israeli air space earlier this week.
The army says the unmanned aircraft was shot down by fighter jets near Mount Sagi in the Negev on Monday.
The army does not say where the drone crossed into Israel from, but Mount Sagi is only a few kilometers from the border with Egypt.
An official statement given on condition of anonymity notes that the drone was unarmed and apparently entered Israel from Egypt after running into technical issues. The downing of the aircraft was coordinated with Egypt, it says.
The army says the incident is being investigated.
It is unclear why the military kept the incident under wraps for two days.
