Apparently., Saudi Arabia views Palestinian expats as a existential threat. Law enforcement agencies there are involved in a major campaign of arrests of Palestinian expatriates who are working on behalf of the Muslim Brotherhood in the Kingdom, where the Brotherhood is banned.
More than sixty Palestinians accused of Muslim Brotherhood affiliation have been arrested and charged; one UK-based NGO has stated that more than 150 Palestinians are in custody there..
Additionally, over one hundred other Palestinians, known to be members of Hamas, have been arrested and deported. They were engaged in fundraising for their entity, which acts constitute the providing of material support to a known terrorist organization.
Given our recent article, which was taken from an interview with the son of Hamas' co-founder, and admits that Palestinians who are Hamas agents are working from Turkey, any Palestinian expat operating from outside the Territories, it is prudent at this time regard any Palestinian expat working abroad as a potential terrorist, until you rule them out through Enhanced Due Diligence investigation.
