WASHINGTON (AP) — The Obama administration is imposing sanctions on two Lebanon-based charities it said are controlled by Hamas.

The Treasury Department said any assets in the US held by al-Waqfiya and al-Quds are now frozen. Americans cannot donate to them.

The department says both groups exist to support families of Hamas fighters and prisoners and programs designed to spread Hamas’ influence in the Palestinian territories.

Hamas doesn’t recognize Israel. The US considers it a terrorist organization.

Also Thursday, the State Department declared Yemen-based Ansar al-Sharia a terrorist body, calling it an alias of al-Qaida in the Arabian Peninsula.

The organization is distinct from the Libyan-based militant group of the same name, which has been identified as a potential suspect in the Sept. 11 attack on the US Consulate in Benghazi.
