Senior officials in Jerusalem said Monday that Israel has received information that organizers of the Gaza flotilla may be bringing chemical substances on the ships to use against Israeli soldiers to prevent them from boarding the ships.

The senior officials also said that Israel had been notified that several extremists among the Gaza flotilla participants had recently claimed that they intend on “shedding the blood of IDF soldiers.”

Moreover, despite earlier reports, it seems that activists from the Turkish organization IHH, which was involved in the deadly IDF raid on the Mavi Marmara in last year’s Gaza flotilla, will be joining several of the ships sailing for Gaza as part of the flotilla.

Israeli officials claim that two activists participating in the flotilla have connections to Hamas. They named the first one as Amin Abu Rashad, who they claim is one of the head Dutch organizers for the Gaza flotilla and had served in the past as the head of the Hamas’ Charitable Foundation in Holland. The foundation closed down following Dutch authorities’ probe into its involvement in funding terror activities.

The second activist is Mohammed Ahmed Hanon, which Israel claims is a Hamas activist who stands at the head of the ABSPP, which is involved in transferring funds to terrorists.
