Al-Jazeera reports:

Dozens of people have been injured in clashes with police after thousands of opponents of President Mohamed Morsi returned to the streets of Egypt, demanding his resignation in the wake of the deadliest violence since he came to power seven months ago.

Protesters braved Cairo rainfall on Friday to march to Tahrir Square and the presidential palace, chanting "Freedom!" and "Morsi is illegitimate!" Some tossed Molotov cocktails at the presidential palace, prompting security forces to respond with water cannon and tear gas.

Scores of protesters clashed with riot police several hundred metres from the square, witnesses said.

Thousands of Egyptians opposed to President Mohamed Morsi who took to the streets again on Friday were met with vollies of tear gas from throngs of state security forces as they pushed for an overthrow of the government amid renewed calls that the revolution that started two years ago remains unfinished.

As evening fell in the country, the Egypt Independent reports the atmosphere was growing "tense" outside the presidential palace in Cairo. Large protests were also reported in Alexandria and in the Suez Canal cities, including Port Said.
