Explosions have been reported at three Egyptian resorts. Hamas has claimed responsibility for at least one of the explosions. A massive explosion occurred at the five-star Hilton Hotel in Taba, Egypt, at around 10 p.m. local time Oct. 7. The hotel was filled at the time with vacationing Israelis, and several casualties were reported, although immediate figures were not available. Reports also indicate that the hotel's ceiling and parts of the interior walls collapsed. Two other blasts have been reported by Egyptian media, in the Dead Sea resort town of Nueba and in the town of Ras al-Satan, both within an hour's drive of Taba, on the evening of Oct. 7. The timing of the blasts suggests they are connected with the Hilton Hotel bombing in Taba, and they come at a time when Jewish travelers flood the Sinai Peninsula. All the evidence coming in from the Taba bombing points toward a suicide car bombing, carried out by members of Hamas. While Egyptian security officials report the explosion occurred amid gas tanks in the hotel's kitchen — which is located next to the hotel casino, where many tourists were gambling — Israeli security forces are reportedly concerned that the blast was caused by suicide bombers. Some blast victims at the hospital reported that suicide bombers were responsible. The hotel is massive — there are 410 rooms — and was likely filled nearly to capacity during the Jewish holidays. Europeans also frequent the resort, which is located on the Red Sea. Oct. 8 marks a Jewish holiday called Shmini Atzeret, held during the festival of Sukkot. Thousands of Israelis take vacations during the month of October, and many of them patronize Red Sea resorts during that time. A blast at a large hotel would result in many casualties. On Sept. 9, the Israeli government warned Israelis against traveling to Egypt, on "concrete" terror threats to tourists on the Sinai Peninsula. Arabic media is carrying reports that Hamas claimed responsibility for the bombing of the hotel, which was most likely a car bombing. Egyptian security forces will likely be frustrated by a suicide bombing. Egypt's government has labored to keep Islamist militants quiet for years, with relative success. However, if Israeli-Palestinian conflict spills over into a neighboring country, it will have serious repercussions. Finally, it is worth noting that the Sheraton and Palestine hotels in Baghdad were hit with rockets during fighting Oct. 7. While the two incidents may not be related, what is important is that neither bombing can be brushed off as mere coincidence. Hotel security should be heightened around the world, especially if the incidents can be connected.
