Fifteen  people was reported dead in Alexandria and three in Cairo in clashes between supporters and opponents of unseat  President Mohammed Morsi, CEOAFRICA news gathered that .

The violence erupted after three pro-Morsi demonstrators were killed by security forces in another part of the capital.

Troops later restored calm in Cairo, but nationwide violence left some 29 dead and 335 injured, officials said.

The army removed Mr Morsi from power on Wednesday after millions of people protested over his leadership.

Mr Morsi, Egypt's first democratically elected leader, is in detention, as are some senior figures of his Muslim Brotherhood movement.

Early on Saturday, state media reported the Brotherhood's deputy leader Khairat el-Shater had been arrested at his Cairo home on suspicion of incitement to violence.

The Tamarod [Rebel] movement - which organised recent anti-Morsi protests - accused the ousted president of pursuing an Islamist agenda against the wishes most Egyptians, and of failing to solve economic problems.

The African Union has condemned what is going on in Egypt and has also suspended Egypt.

Federal Government of Nigeria has also condemned the crisis in Egypt and direct that the Army should immediately return power to democratically elected Government.

UN Secretary General Ban Ki-moon has also expressed worry over the violence, saying that it was for the people of Egypt to determine the way forward - and all people, including women, needed to be part of that process.
