The Anti-Coup Alliance in Egypt calls for fresh week-long protests against President Abdel Fatah el-Sisi.

The alliance, led by the banned Muslim Brotherhood movement, says the aim of the nationwide rallies is to call for the release of all political prisoners detained since the ouster of former President Mohamed Morsi in 2013.

The opposition groups also held nationwide anti-government rallies on Friday to demand an immediate end to the military rule government in Egypt.

“Our brothers and sisters are being held in prisons and are subjected to humiliation and police brutality for what? Just for expressing their views and opinions. This is unfair,” a protester told Press TV.

The Friday protests were mostly peaceful, but several incidents took place in the coastal city of Alexandria where unknown assailants set fire to a public bus hours after a bomb exploded near a police station that left no casualties.

The Muslim Brotherhood members say they continue weekly protests in a build up to the next anniversary of the 2011 revolution that toppled former dictator Hosni Mubarak.

Egypt has been the scene of massive anti-government protests, with continuous clashes between security forces and supporters of Morsi.

Morsi was Egypt’s first democratically-elected president, and was ousted in July 2013 in a military coup led by el-Sisi, the then head of the country’s armed forces.

Rights groups say the army’s crackdown on the supporters of Morsi has left over 1,400 people dead. Some 22,000 people have been arrested, while dozens have been sentenced to death in mass trials.
