The Guardian reports: Egypt suffered renewed outbreaks of violence on Friday as Muslim Brotherhood offices were attacked in at least four provinces two days before the scheduled start of mass protests against the president and Brotherhood associate Mohamed Morsi.

Two people were killed in Alexandria on Friday – one an American bystander who was watching an attack on local Brotherhood offices – and 70 were injured. Clashes were reported in several other cities between Morsi’s often secular-minded critics – who seek his immediate resignation – and his allies in the Muslim Brotherhood and other Islamist groups, who defend his democratic legitimacy.

Six people have now been killed in the renewed violence this week. According to Brotherhood officials, a former MP from their political wing was among the dead on Thursday.

Egypt Daily News reports: On Friday thousands of protesters vowed to remain in Tahrir Square in their call for the ouster of President Mohammed Morsi, and many started erecting tents in preparation for mass demonstrations on 30 June.

Marches from various locations in Cairo, including Talaat Harb Street, Mostafa Mahmoud and Sayeda Zeinab, brought in thousands of protesters into the square in the afternoon.

“We are staying for the long run, we are not leaving before [Morsi] does,” yelled one protester in the square.
