Street art in the Egyptian revolution

It's the beginning of the revolution in 2011 and young Egyptians hold together in the face of former President Hosni Mubarak's oppressive regime.

A graffiti made in the early days of the protests has slogans which say, "Revolution is in our veins."

Another mural by Ammar Abo Bakr, painted at Mohamed Mahmoud Street, shows a tearful boy holding a piece of bread.

This mural depicts the brutal beating and murder of Egyptian blogger Khaled Said in 2010.

This street painting shows Egypt's former ruler Hosni Mubarak, former military chief Mohamed Tantawy and former President Mohamed Mursi. The words in Arabic read, "No, the Brotherhood's Constitution, it's valid."

Street artists used images like these to communicate their dissatisfaction with the regime and to also create awareness about the plight of ordinary people

Graffiti artists often painted on the walls in Mohamed Mahmoud Street, the center of clashes between protesters and security forces in Cairo in 2011.

It's 2014, and ousted ruler Hosni Mubarak has been released from prison. Will President Abdel-Fattah el-Sissi lose his popularity? This painting shows a man with a clown mask holding ancient Egyptian scepters of kinship.

This mural by Ammar Abo Bakr was made in Berlin in 2015, following the death of Shaimaa al Sabbagh, an Egyptian poet and activist.

This recent picture that was painted by Polish artist Lukasz Zasadni adorns the walls of a cemetery in Cairo. Street murals are no longer very common in Egypt.
