Hamas' military wing has claimed responsibility for the launch of three rockets at Tel Aviv Ben Gurion airport after US and some European airlines had resumed flights.
A statement from the Palestinian militant group said: "At 11.45am (8.45 GMT), the Qassam Brigades bombarded Ben Gurion airport with three M75 rockets."
An Israeli military spokeswoman confirmed to AFP that missiles were fired from Gaza. The European Aviation Safety Agency has lifted a recommendation that airlines refrain from flying to Tel Aviv airport.
But Germany's two largest airlines, Air Berlin and Lufthansa, said they are not yet resuming flights to Ben Gurion.
Lufthansa said it "acknowledges the considerable efforts made by Israel to provide the best possible protection for Ben Gurion Airport" with its missile defense system. It said flights will resume "as soon as this protection can be verifiably guaranteed".
The US Federal Aviation Administration also lifted the recommendations but warned that the situation remained "very fluid".
According to flight trackers, Air Canada flight AC84 circled over southern Israel several times on Friday because it was unable to land in the airport.
