The August 2012 Sinai attack occurred on 5 August 2012, when armed men ambushed an Egyptian military base in the Sinai Peninsula, killing 16 soldiers and stealing two armored cars, which they used to infiltrate into Israel. The attackers broke through the Kerem Shalom border crossing to Israel, where one of the vehicles exploded. They then engaged in a firefight with soldiers of the Israel Defense Forces, during which six of the attackers were killed. No Israelis were injured.

The original attacks occurred in three coordinated stages. They were carried out by 12 militants in four groups dispersed over an area 12 kilometers long. three militants spread out about 200 meters from one another, armed with suicide bomb vests, grenades, RPGs, and machine guns opened fire on an Egged passenger bus on line 392. According to eyewitnesses, a white car was following the bus, and a group of people dressed in military uniforms got out and opened fire. The bus driver, Benny Belevsky, did not stop the bus and sped away, getting to an IDF post near the Netafim Border Crossing.
The militants, dressed in brown uniforms resembling those of the Egyptian Army, then began attacking passing vehicles, waving white handkerchiefs to fool motorists. One of the militants attacked a bus that drove by and detonated the suicide bomb belt he was wearing, killing himself and the bus driver, who had stopped the empty bus. Another militant opened fire at a passing car and killed the female driver. The same militant then fired an RPG at an Israeli Air Force helicopter, but missed.
Around 13:30, not far from the first shooting incident, militants opened fire, including with an anti-tank missile, at a bus and private car on route 90, a desert road near the border with Jordan. According to medics, five people were killed in the attacks. Seven people were wounded when another private vehicle was hit by an anti-tank missile.
