A human rights group says the US and the European Union should cut off funds to Palestinian security services until accusations of abuse against protesters are investigated.
Human Rights Watch says Palestinians demonstrating in support of Egypt's anti-government protest movement were assaulted on three occasions, most recently at a 5 February rally.
The rights group says plainclothes officers groped women and detained one man, accusing him of tearing down a poster of Palestinian President Mahmoud Abbas.
The group also said Abbas should order an investigation into the death last year of a Palestinian man allegedly tortured by interrogators.
