The United Kingdom and the United States imposed targeted sanctions on half a dozen Hamas leaders and financiers to hobble the organization’s operations in Gaza and elsewhere, according to a statement released Tuesday by Britain’s Foreign Office, Paralel.Az reports citing CNN.

The UK and the US have hit four of Hamas’ senior leaders and two of its financiers with travel bans, asset freezes and arms embargoes, according to the statement. The UK and the US had already designated Hamas as a terrorist organization.

“We will continue to use every tool at our disposal to disrupt the abhorrent activity of this terrorist organization, working with the United States and our other allies, making it harder for them to operate and isolating them on the world stage,” UK Foreign Secretary David Cameron said in a statement Tuesday.
