Security forces have intensified their presence around Egypt’s capital in anticipation of protests by supporters of ousted president Mohamed Morsi, Al-Ahram Arabic news website reported.

The interior ministry increased the security presence in front of police stations, vital institutions and churches on Friday morning.

The major pro-Morsi coalition, the National Alliance to Support Legitimacy, has called on supporters of the ousted president to launch a wave of protests starting Friday, to be escalated on Sunday when Egypt’s new president elect, Abdel-Fatah El-Sisi, is sworn into office.

The Muslim Brotherhood-led coalition insists Morsi is still Egypt's legitimate president, despite his removal last summer after mass protests against his rule, and a subsequent presidential election last month which El-Sisi won.

The group describes Morsi – who currently faces charges including inciting murder and espionage – as the "kidnapped president".

The government has declared the coming Sunday an official holiday for the public sector in celebration of the swearing-in ceremony. For schools and universities, however, Sunday is a normal working day. 

Security forces have been subject to repeated militant attacks since Morsi's ouster last summer. The government alleges that Morsi's Muslim Brotherhood is behind the violence, which has killed around 500 police and military personnel, although the Brotherhood has denied it is responsible.
