The United States has imposed sanctions on the United Nations expert who investigates human rights abuses in occupied Palestinian territories, the latest effort by the Trump administration to punish those who criticize Israel's war in the Gaza Strip.

“It's a dangerous precedent because it creates a chilling effect for all special rapporteurs,” said Agnes Callamard, head of human rights giant Amnesty International and a former UN special rapporteur on extrajudicial, summary or arbitrary executions.

UN rapporteur Francesca Albanese tells Al Jazeera the move is retaliation for ‘pursuit of justice’ in Israel’s Gaza war.
