Israeli Government Cancels Flights of Peace Activists

Not novel in itself, but the scale is pretty impressive.  It looks like at least hundreds and maybe thousands of cancelled tickets.  In one case (Lufthansa) an entire flight was cancelled: " Jet2.com has been informed by the Israeli authorities that you will not be not permitted to enter Israel. Consequently, if Jet2.com carries you to Israel, you will be refused entry and Jet2.com will be liable for both a fine and your return to Manchester."
