Britain's designation of Hamas as "terrorist" sparked criticism from Yemeni Supreme Political Council member Mohammed Ali al-Houthi, who condemned the designation.

"We condemn the designation of Hamas as terrorist, even if it was not surprising from Britain, the founder of the Israeli occupation," al-Houthi said Saturday on Twitter.

"When the designation coincides with the anniversary of the criminal Balfour Declaration, it is proof that Britain continues to terrorize the victim and support the criminal entity," he further added.

The senior Yemeni official went on to say the designation was "political," asserting that the decision will only add to the determination of Hamas and its supporters to liberate occupied Al-Quds and all of Palestine.

British Home Secretary Priti Patel will be announcing a plan to make support for Hamas illegal in the United Kingdom through legislation that prohibits all support for the Palestinian group, and supporters could face up to 14 years in jail, The Guardian reported Friday.

Patel claimed that this step would "help to combat antisemitism," explaining that anyone who expresses support for Hamas, arranges meetings for the resistance group, or even flies their flags will be in breach of law.

Hamas regretted the British decision to designate it as terrorist, and to threaten all those who support it with jail time.

Palestinian resistance factions also condemned the UK's designation of Hamas as "a terrorist organization," underscoring that it "exposes the UK's pro-Zionist policy since the Balfour Declaration.
