Hezbollah’s attackers have ‘intimate’ knowledge of the organisation 

United Against Nuclear Iran Senior Advisor Dror Doron discusses the detonation of Hezbollah-owned communication devices killing 37 and injuring thousands.
Israel has not claimed responsibility for the attack but is assumed to be the responsible party.
“What we can assume by now is that whoever committed this operation had a very intimate knowledge of Hezbollah, of Hezbollah’s way of acquiring communication equipment from abroad,” Mr Doron told Sky News Australia.
“Out of the 4,000 people hurt in Lebanon due to this operation, the overwhelming majority were Hezbollah’s operatives.
“That’s a very highly targeted operation and I think security professionals and counter-terrorism professionals are going to study for many years to come.”
