The Israeli army on Friday detonated two of its espionage devices in southern Lebanon, slightly injuring two passers-by, the Lebanese military said. "Around noon today, the Israeli enemy detonated two spying apparatuses by remote control in Wadi al-Qaysiyya outside of Majdal Selem" near the southern coastal city of Tyre, an army spokesman said. Two laborers in the area suffered light injuries, he said. The spokesman did not give details on the devices destroyed. Hezbollah, for its part, said the incident was "another achievement" of the Shiite movement's counter-espionage teams. "Telecom technicians of the resistance managed to discover a spying device the enemy had planted in Wadi al-Qaysiyya," said a statement released by the Hezbollah media relations department. "The enemy detonated its devices as a result of the discovery," the statement added. Friday's incident came amid high tension in Lebanon over impending indictments by a UN-backed probe into the 2005 assassination of ex-premier Rafiq Hariri. The Special Tribunal for Lebanon is allegedly set to implicate high-ranking members of Hezbollah in the killing, a move the party has repeatedly warned against. Hezbollah has accused the STL of being part of a US-Israeli plot and said Israel had infiltrated the group's telecom network. The STL has allegedly based its indictments on extensive telecommunications evidence.
