At least seven people have been killed and hundreds more injured during Egypt’s ‘Day of Rage’ mass protests against the government of President Mohamed Morsi.

Security and medical sources said Monday that the June 30th anti-regime rallies in the city of Asyut left three dead while several others were also wounded.

The others were killed in the cities of al-Fayoum and Bani Suwaif. 

The casualties came when calls for mass demonstrations by the Egyptian opposition were met with counter protests by followers of Morsi and the ruling Muslim Brotherhood.

On Sunday, anti-government protesters flooded the streets across Egypt, calling for the resignation of the Egyptian leader.

Mass rallies came a year after Morsi was elected president following the 2011 revolution that toppled the Western-backed regime of Hosni Mubarak.

“The people want the ouster of the regime,” the protesters chanted in the capital Cairo's iconic Liberation Square.

The demonstrators are angry at Morsi's handling of the economy and failure to fulfill his electoral promises. The organizers of the major demonstration for Sunday claim that more than 22 million people have signed petition for the resignation of the president and a snap election.

Anti-government protests were also staged in the coastal city of Alexandria, the Nile Delta cities of Mansura, Menuf, Tanta and Mahalla, the canal cities of Suez and Port Said as well as Zagazig.

Meanwhile, pro-Morsi demonstrators have held rival rallies in support of the president as they say he needs time to implement the changes demanded by the Egyptians.

Reports say clashes broke out between supporters and opponents of Morsi after protesters marched to the office of the Freedom and Justice Party (FJP), the political arm of the Muslim Brotherhood.

Dozens also attacked the Brotherhood headquarters in Cairo with petrol bombs, birdshot and stones, according to Gehad al-Haddad, a spokesman for the movement.
