The real story, according to Lebanese security officials, is that the explosion occurred while the extremist militants of Jund al-Sham tried to prepare a bomb in the tire shop. The Lebanese security officials said that some of Jund al-Sham members were extracting TNT from a 107 mm shell, apparently to use it in making a bomb.
Among those lightly wounded was a leader of Jund al-Sham, Shehadeh Jawhar, also known as Abu Omar, according to residents and Abu Sharif, the officials said.
Residents said the two dead men were the shop owner ... Jawhar's uncle ... and his nephew.
Also wounded was a Lebanese man named Mohammed Ghuneim, whose brother, Shadi, has been held for months in Saudi Arabia for suspected links with al-Qaida, the security officials said.
Since the Lebanese army and security personnel cannot enter the Palestinian refugee camps, based on the absurd "Cairo agreement" that was agreed on in 1969, the camps have become breeding grounds for terrorism. A number of small, little known Islamic militant groups proclaiming a Jihadist (holy war) ideology have arisen in recent years in Lebanon's Palestinian refugee camps, which have long been home to numerous Palestinian militias.
Jund al-Sham, which is Arabic means literally "Soldiers of Damascus", is a splinter group from another Palestinian militant group called Asbat al-Ansar based in Ein al-Helweh.
Gotta love those "work accidents."
