The United States and Britain imposed a fresh round of sanctions on Tuesday targeting Hamas as they seek to cut off funding for the militant Palestinian group following its deadly attack on Israel last month.

The United States announced its third round of sanctions since the attack, targeting key Hamas officials and the mechanisms through which Iran provides support to Hamas and its ally Palestinian Islamic Jihad (PIJ), another militant group.

Britain added six new designations to its counter-terrorism sanctions list, including four individuals linked to Hamas, an update to the UK government website showed.
