In Egypt, at least 17 people have reportedly been killed as security forces cracked down on protests by supporters of the banned Muslim Brotherhood.
Deaths were reported on January 3 in Cairo, Alexandria, Ismailia, Fayoum, and Minya.
The Health Ministry said more than 50 people were injured, and the Interior Ministry said 122 Muslim Brotherhood supporters were arrested.
A Muslim Brotherhood-led alliance said the death toll was actually 19.
Security forces moved in as thousands of people protested in defiance of a ban on demonstrations.
Hundreds of people have been killed in clashes and thousands imprisoned since the military overthrew Islamist-backed President Muhammad Morsi in July.
Clashes have intensified since the authorities officially declared the Muslim Brotherhood a terrorist organization last month.
The violence comes with the authorities preparing to hold a vote on a new constitution later this month.
