Cyprus officials have admitted that the person was given to them by Israeli intelligence, a few weeks before Burgas. It seems like it would be extremely in Israel's interest to either explain or concoct an explanation of how vast details were known of this one case, but a very similar, obviously related case, went utterly under the screen. It gives the appearance so far that Israel let Burgas go in order to have more political ammunition against Hezbollah in Europe. Many things support that.
