Hamas (including its military wing, the Izz-al-Din al-Qassem Brigades) is subject to an EU asset freeze under Council Regulation (EC) No. 2580/2001. The Terrorism (United Nations Measures) Order 2009 provides enforcement provisions in the UK in respect of this Regulation. Hamas' military wing is also proscribed in the UK.
As such, any financial institutions or other persons that hold or operate accounts for Hamas (including its military wing) are required to freeze those accounts. In addition, the asset freeze prevents financial institutions and others from making funds, economic resources or financial services available to Hamas.
The prohibitions in the Terrorism (United Nations Measures) Order 2009 apply to persons in the UK and British citizens elsewhere, including corporate bodies incorporated or constituted under the law of any part of the UK or a Scottish partnership, including banks, financial institutions, charitable organisations and non-governmental organisations, in the UK or established under UK law.
