Handle With Caution -DEBKAfile is not a particularly reliable source: DEBKAfile reports that Arab Internet sites, most of them Jordanian, claim that 10 days ago on Oct. 12, Meir Dagan, the head of Israel’s external intelligence service, the Mossad, was targeted by assassins while visiting Amman. Some describe a large bomb explosion alongside his convoy and add that Israeli and Jordanian guards with the convoy were injured. Others say Dagan himself was hurt or even killed in the attack. They claim Israel and Jordan are keeping the incident a secret.
