The Saudi ISIS account has been debited money before the attack

Before Easter day attack, the Israeli intelligence service, Whitestream, has uncovered that a large sum of money has been deposited to the Saudi-based Bitcoin account of the ISIS.
The account has increased to $ 4.5 million from $ 500,000.
But it has dropped again to $ 500,000 as of the day of the attack.
It is said to be the same amount that had been maintained for a nine month period. However, the US intelligence agency has revealed that the deal had been carried out via a company located in an island in Canada.
All this has been revealed by a Israeli business newspaper.
