Israeli defence against Iran attack overnight 'likely cost over $1bn'

Israel likely used over $1bn worth of defensive systems to stop Iran's attacks overnight, according to a former financial adviser to Israel's military. 

"The defence tonight was on the order of 4-5bn shekels [$1-1.3bn]," estimated Reem Aminoach, former financial adviser to the Israeli military's chief of staff, in an interview with Israel's Ynet news. 

"If we're talking about ballistic missiles that need to be brought down with an Arrow system, cruise missiles that need to be brought down with other missiles, and UAVs, which we actually bring down mainly with airplanes - then add up the costs - $3.5m for an Arrow missile, $1m for a David's Sling, such and such costs for airplanes. An order of magnitude of 4-5bn shekels."
