The lesson here is that even junior HAMAS members are reportedly engaging in financial crime and terrorist financing. Whilst their financial activities in EU countries may be personal, it is becoming dangerous to bank any HAMAS agents. If Israel has stated that minor politicians are involved, you can rest assured that the US has that evidence, and will take the same position, should its law enforcement agencies find that you are banking them.

You do not want to be targeted as an institution of primary money laundering concern.This is not a political statement, but a recognition of the reality on the ground in the global war against terrorism. To bank even minor players from designated terrorist organisations is an invitation to disaster. 

Remember also, as bulk cash smuggling operations continues to be the principal means of funding HAMAS activities in the Palestinian Territories, that even low-level HAMAS members can be involved in moving what has been designated as terrorist funding. Bank them at your peril.
