Egyptian authorities say at least 13 people were killed Friday across Egypt, as police moved to disperse thousands of Muslim Brotherhood supporters seeking reinstatement of ousted president Mohamed Morsi.
Witnesses said police moved in quickly to disperse the rallies, which took place in Cairo, Ismalia, Alexandria and Giza. Authorities earlier warned they would not tolerate further Brotherhood protests, following last month's designation of the Islamist group as a terrorist organization.
Egypt's health ministry said five of the victims were killed in Cairo, but did not say whether they were police, demonstrators or bystanders. More than 120 people were reported arrested.
The military-backed government, which removed Mr. Morsi from office last July, has been using the "terrorist" designation to detain hundreds of Brotherhood supporters. Thousands more, including top Brotherhood leaders, have been jailed for months.
Since the July 3 ouster, Mr. Morsi's supporters have staged repeated protests calling for his reinstatement, with many of the rallies occurring after Friday prayers in Cairo and other major cities.
Mr. Morsi, the country's first democratically-elected president, is on trial on charges of inciting the killings of protesters during his one-year presidency. He faces an additional trial in late January for a jailbreak during the 2011 popular uprising that toppled his predecessor, long-time ruler Hosni Mubarak.
