Fighting in the Egyptian capital of Cairo has intensified following the death of three protesters on Friday.
Islamist supporters of deposed president Mohamed Morsi have been clashing with opponents of the former leader.
Witnesses report fireworks being thrown as the groups battle to gain a hold on Tahrir square, in central Cairo. The square is one of the key places in the city where both groups hope to hold demonstrations.
Both sides have been using the main bridges crossing the river Nile to reach the square, but have been subsequently blocking them off. There have also been reports of army tanks on the 6th October bridge.
Meanwhile the Egyptian Health Minister Mohamed Mostafa Hamed has said that six people have been killed in protests nationwide.
Five Egyptian police officers have been reported as shot dead in separate incidents in the north Sinai town of El Arish. It is unclear if these shootings are connected to the unrest in Cairo.
