Al-Khalifa on Wednesday called the ban “temporary.”
The Obama administration has been criticized for not supporting the pro-democracy movement in Bahrain as it has in other Arab Spring countries. Republican candidate Mitt Romney has declined to challenge President Obama on the issue.
The United States is increasingly isolated, however. Great Britain has criticized Bahrain, despite signing a defense cooperation agreement with the country earlier this month.
“A blanket ban of this nature is excessive,” Alistair Burt, the British minister for the Middle East and North Africa, said Tuesday.
“Peaceful protest is a democratic right. I hope the Bahraini government will rescind this measure as quickly as possible.”
The human-rights group Amnesty International has also weighed in.
“Even in the event of sporadic or isolated violence once an assembly is underway, the authorities cannot simply declare a blanket prohibition on all protests," Hassiba Hadj Sahraoui, the Middle East and North Africa Program deputy director at Amnesty International, said in a statement.
"Such a sweeping measure amounts to nothing less than nullifying the rights to freedom of association, expression and assembly. Law enforcement officials must act to protect peaceful protesters rather than using the violent acts of a few as a pretext to restrict or impede the rights of all.”
