An unidentified group threw Molotov cocktails into a second-storey Mansoura government office during mass protests in the area Wednesday evening.
According to report, the subsequent fire destroyed the office's air conditioning unit, blinds, furniture and numerous documents.
Building security personnel attempted to put out the fire using extinguishers, but failed to douse the flames completely.
Civil defense forces and central security officers arrived on scene after 20 minutes and were able to prevent the fire from spreading to other buildings.
Daqahliya Governorate has been a flashpoint for unrest recently, with protesters taking to the streets against President Mohamed Morsy and the Muslim Brotherhood. More often than not, the protests results in clashes and tear gas. Demonstrators have also blocked streets and set tires on fire in acts of civil disobedience.
