Following are key developments in Egypt since millions took to the streets Sunday to demand the resignation of Islamist President Mohamed Morsi, a year after he took the oath of office

- Sunday, June 30:

- Chanting "Leave!" and "the people want the ouster of the regime," crowds demonstrate across Egypt in response to a call from the grassroots movement Tamarod -- Arabic for rebellion.

- In Cairo the protesters gather around the presidential pa

ace and in Tahrir Square, epicentre of Egypt's 2011 revolution.

- Huge demonstrations also take place in Alexandria, Menouf and Mahallah in the Nile Delta, and in the canal cities of Suez and Port Said.

- The army speaks of "several million" protesters and a military source tells AFP: "It is the biggest protest in Egypt's history."

- Morsi supporters rally in the Cairo district of Nasr City. The army puts their numbers at 25,000.

- At least 16 people are killed nationwide, eight during clashes between government supporters and opposition forces outside the Cairo headquarters of the Muslim Brotherhood, the health ministry says.

- Morsi calls for dialogue, which Tamarod rejects, saying there is no alternative to his resignation.

- Opposition leader Hamdeen Sabbahi presses the army to support opposition forces if Morsi does not step down.

- In Tahrir Square, anti-Morsi protesters erupt in joy on hearing the army's statement.

- Tuesday July 2:
