Egyptian army and police forces have placed a siege on Yahya mosque in Alexandria to prevent the arrival of anti-coup protesters.
The Anti-Coup National Alliance announced that the Mosque would be one of the gathering points for the anti-coup protests.
Army and police forces encircled al-Fatah mosque in Ramses Square in Cairo on Friday. The siege continued from Friday 5pm until Saturday midday, when the army and police forces opened fire on the mosque and broke into it.
The ministry of interior claimed that unknown people had shot at the military from the top of the mosque's minarets, although there was no evidence of this.
More than 200 protesters were killed during a crackdown on Friday's protesters, including three who died during the siege of the mosque.
