Yesterday, Israel issued an urgent warning to some 35,000 (or maybe 550) vacationing Israelis to leave the Sinai immediately, as they were in danger of being kidnapped.
Egypt responded harshly, saying that the threat was exaggerated and meant to harm the Egyptian tourism industry. (This is typical - the Arab idea that every Israeli action is purely meant to harm Arabs.)
Firas Press is reporting that there was a kidnapping of an Israeli in the Sinai today but that military censor stopped publications of that report. No details were given. JPost mentioned rumors to that effect but said that there was no concrete evidence of a kidnapping.
