The Egyptian authorities removed on Wednesday one of the security walls, located in Qasr al-Aini street, which had been built by the military in downtown Cairo to prevent recurring confrontations from reaching state buildings.
Army bulldozers began removing one of the concrete wall to reduce traffic congestion in this crowded part of the city.
In November 2011, the military erected a number of cement walls following a series of violent clashes between security forces and protesters, which are better known as the Cabinet and Mohamed Mahmoud clashes.
However, the authorities did not remove other concrete barriers that block downtown streets, citing security reasons.
Graffiti artists have used these walls to commemorate people who died since the beginning of the three-year old uprising and also to express their political stances.
