Israel carried out a pager bomb attack in Lebanon and Syria, leaving 12 dead and 2,800 injured, fearing that Hezbollah was close to uncovering their espionage plot, according to a new report. Security sources believe Mossad, Israel's spy agency, intercepted devices en route to Lebanon and attached explosives to be used when needed. Questions remain as to why the attack was carried out on Tuesday. Israel's domestic security agency recently foiled a plot by Hezbollah to assassinate a former senior defence official. Thousands were injured when pagers across Syria and Lebanon exploded on Tuesday.
