"The implementation of Egypt's restrictive demonstrations law has led to an increase in arrests, detentions, and charges against opposition figures, human rights activists and peaceful demonstrators, and sends a chilling message to civil society at large," State Department spokesperson Jen Psaki said.
The US denouncement came a day after three activists in Egypt were jailed for organising an unauthorised march to protest new law banning all but police-sanctioned protests.
"We continue to urge the government to fulfil its commitment to implement an inclusive democratic transition, including by permitting an open environment in which Egyptians are free to campaign and vote in favour or against the draft constitution on January 14-15, or abstain from the process entirely," Psaki said.
