Supporters of former Islamist president Mohamed Morsi staged demonstrations across a number of governorates on Friday, a weekly occurrence since his ouster in July.
Hundreds demonstrated in Cairo, Giza, Alexandria, the Nile Delta governorates of Tanta, Kafr El-Sheikh and Menoufiya, and the Upper Egypt governorate of Fayoum, Al-Ahram Arabic news website reported.
Some of the rallies were dispersed with teargas.
Three protesters were arrested in Giza and ten in Alexandria.
The Muslim Brotherhood-led National Alliance to Support Legitimacy had called for another week of protests against the Egyptian authorities. Since Morsi's ouster, his supporters have been holding weekly demonstrations, which have become noticeably smaller in scale.
The Brotherhood's leadership and thousands of its supporters are currently behind bars, being tried and investigated for an array of charges.
The group has been designated a terrorist organisation by the Egyptian authorities, but it denies being engaged in any form of violence.
