WASHINGTON: The US Treasury Department on Tuesday imposed sanctions on a major Palestinian legal group for prisoners and detainees along with five other charitable entities across the Middle East, Africa and Europe, accusing them of supporting Palestinian armed factions and militant groups, including Hamas’ military wing, under the pretense of humanitarian aid in Gaza.

Those sanctioned include Addameer, a nongovernmental organization that was founded in 1991 and is based in the city of Ramallah in the Israeli-occupied West Bank.

The Palestinian group provides free legal services to Palestinian political prisoners and detainees in Israeli custody and monitors the conditions of their confinement.

The federal government claims that Addameer “has long supported and is affiliated” with the Popular Front for the Liberation of Palestine, a secular, left-wing movement with a political party and an armed wing that has carried out deadly attacks against Israelis. Israel and the United States have labeled the PFLP a terrorist organization.

Addameer did not immediately have a comment on the sanctions.
