Clashes erupted on Wednesday between hundreds of supporters and opponents of Egypt's Islamist President Mohammad Mursi in the Nile Delta city of Mansura, which resulted in one person killed and dozens others injured.

Clashes were violent and left more than 160 people were injured, most of them opponents of Morsi. Local media reported that injuries were due to the use of live bullets and bladed weapons.

Also 25 people at least were injured in clashes between supporters and opponents of Mursi in the eastern province of Egypt, where opponents set fire to the headquarters of the Freedom and Justice Party's ruling in the eastern town in the Abrahamic.

Russia Today website reported that the demonstrators besieged on Tuesday evening the Muslim Brotherhood’s Mufti, Abdul Rahman Al-Berr and other supporters of the Muslim Brotherhood inside one of Abrahamic mosques, where Berr was casting a sermon.

As a result, clashes broke out between the two parties followed by the arrival of security forces who fired the tear gas. Later on the dissidents set fire to the headquarters of the Freedom and Justice party.

The clashes come amid widespread tension ahead of mass anti-Mursi rallies planned on Sunday to demand the ouster of Mursi and the repair of deteriorating economic situation in the country, while Islamist parties have called for their own rallies to support the president on Friday, raising fears of more unrest.

A campaign dubbed Tamarod (rebellion in Arabic) has collected more than 15 million signatures in support of a snap presidential election just a year after Mursi took power.
