Hundreds of protesters who support Egypt’s Muslim Brotherhood stormed the Giza governorate’s main building and torched it on Thursday, the state-owned news agency reported.
The protesters threw Molotov bombs at the building until it caught fire.
They also prevented the fire department vehicles from reaching the torched building and set the vehicles on fire as well, state TV and witnesses said.
For its part, the security forces fired teargas bombs and deployed soldiers to disperse the protesters.
Violence broke out across Egypt on Wednesday, leaving more than 500 people killed and thousands injured. The situation escalted following the crackdown on the Cairo protest camps for Islamist supporters of deposed President Mohamed Mursi.
