In his trials, Morsi insisted he is the legitimate president and described his toppling as a military coup.

The military-backed authorities dispersed Morsi's supporters' two main camps in Cairo on Aug. 14, 2013. Waves of violence and terrorist attacks escalated in the country following the security crackdown on the Islamists that killed nearly 1,000 and put thousands in jails.

In retaliation, the militants Islamist launched anti-security operation based mainly in the restive Sinai and then crept into the other cities. Hundreds of police and army men were killed in terrorist operations.

Few hours after announcing the death penalty verdict against Morsi, four people, including three judges, were killed in the northern Sinai city of al-Arish when militants shot at their vehicle. The interior ministry said a policeman was also killed by gunmen near Cairo.

The National Alliance for Supporting Legitimacy, a pro-Morsi bloc, has called Saturday for extended revolutionary protests until July 3, the anniversary for Morsi's ouster, under the title of "victory or retaliation."

The alliance said in a statement it will continue its path till the fall of the current regime, and liberate their legitimate president.
