The Trump administration announced on Wednesday it was issuing sanctions against an independent official tasked with investigating human rights abuses in the Palestinian territories, the latest effort by the United States to punish critics of Israel’s 21-month war in Gaza.

The state department’s decision to sanction Francesca Albanese, the UN special rapporteur for the West Bank and Gaza, comes after a recent US pressure campaign to force the international body to remove her from her post failed.

Albanese, a human rights lawyer, has been vocal in calling for an end to what she describes as the “genocide” that Israel is waging against Palestinians in Gaza. Both Israel and the US, which provides military support, have strongly denied that accusation.

Israel has faced accusations of genocide at the International Court of Justice and of war crimes at the ICC over its devastating military assault on Gaza. Albanese’s position has also been backed by leading genocide scholars and rights organisations.
