American officials on Thursday, July 19 identified the suicide bomber responsible for a deadly attack on Israeli vacationers in the Bulgarian city of Burgas as a member of a Hizballah cell that was operating in Bulgaria and looking for such targets, corroborating Israel’s assertions and making the bombing a new source of tension with Iran, The New York Times reported. A senior American official said the current assessment was that the bomber, who struck Wednesday, killing five Israelis, had been “acting under broad guidance” to hit Israeli targets, and that the guidance had been given to Hizballah by Iran, its primary sponsor. A senior Israeli official said that the attack was part of a wave of terrorist attacks around the world carried out by the Iranian Quds Force, an elite unit within Iran’s Islamic Revolutionary Guards, as well as by Hizballah.
