The Israeli Air Force was on maximum alert on Wednesday due to the "infiltration of objects into Israeli airspace" which was closed as a result. All air traffic in and out of the country's Ben Gurion Airport was suspended for some time. The alert came just days after an unmanned drone, believed to have been launched by Hezbollah, was shot down by Israel over the Negev Desert.
A number of military reconnaissance aircraft were scrambled and anti-aircraft missile batteries were deployed in case the "objects" were hostile. There has been no confirmation of what they actually were. In fact, according to Israel military radio, the alert turned out to be a false alarm, and the airspace was reopened for civilian traffic after several minutes.
Palestinian sources report increased activity by the Israeli air force over the occupied West Bank and the 1948 Armistice ("Green") Line during the alert.
