Attempted attack on Israeli border highlights militant presence in Sinai

One soldier from the Israel Defense Forces was killed and another wounded in an attack on the Sinai border today, while three militants were killed.

Israel said it disrupted an attempted large-scale terrorist attack on its southern border today, underscoring the ongoing threat posed by militants in the Sinai peninsula, who have stepped up their attacks since Egypt's popular uprising last year.

Israel's military said it killed three militants who crossed into Israel midday near Har Harif with weapons and explosive belts. One soldier from the Israel Defense Forces (IDF) was killed and another wounded in the exchange of fire. The last time an Israeli soldier was killed by militants from the Sinai was August 2011, according to the IDF.

Israel has long been concerned about security in the Sinai peninsula, which it captured in the 1967 Six-Day War but ceded after making peace with Egypt in 1978.

Former Egyptian President Hosni Mubarak's regime responded harshly to terrorist attacks in the peninsula, particularly after a 2004 attack that killed 34 in the tourist city of Taba, as The Christian Science Monitor's Dan Murphy pointed out recently. But with Mr. Mubarak's ouster last year and the formation of a new government dominated by the Islamist Muslim Brotherhood, Israel has voiced concern that Egyptian security in the Sinai has taken a backseat. 

The deterioration in security has been bad for both sides, however. In August, 16 Egyptian border guards and soldiers were killed, which prompted Egyptian President Mohamed Morsi to summarily dismiss Defense Minister Mohamed Hussein Tantawi and other top military leaders.

Israel has been building an extensive fence along the Sinai border, which is nearing completion. The Israeli soldiers attacked today were guarding a section of this fence. It's not the first time it has been attacked; in June, two militants attacked IDF contractors involved in building the fence, eliciting a strong statement from Israeli Defense Minister Ehud Barak that the new Egyptian president must "swiftly" put an end to attacks from the Sinai.

While many have speculated that the Egypt-Israel peace deal could falter under Islamist rule in Cairo, the Sinai poses a challenge for both nations. If they don't find a way to work together, they both may suffer.
