Police fires tear gas at pro-Morsi rally over the 6th of october Bridge in mid-July (Reuters)
Twelve houses were torched in Cairo's Ezbet Abu-Hashish working-class neighbourhood late on Sunday night after clashes erupted in the area.
Head of Egypt's Civil Protection Authority Abd El-Aziz Tawfik said that eight fire-fighting vehicles arrived at the scene to extinguish the flames, state news agency MENA reported.
Security forces have been inspecting the damage and conducting an investigation.
Conflicting reports have emerged on how the clashes broke out.
Gunshots and Molotov cocktails were used in clashes between the two local families of El-Ghagar and El-Fotaima, according to Al-Ahram Arabic news website.
According to eyewitnesses quoted by MENA, tens of supporters of deposed president Mohamed Morsi threw Molotov cocktails at homes from the nearby Sixth of October Bridge.
Other media reports said that a pro-Morsi march passed by Ezbet Abu-Hashish when arguments broke out between protesters and residents, turning into violent confrontations.
Security forces had closed off one side of the Sixth of October Bridge during the clashes, but reopened it when the situation stabilised.
After one year in office, Morsi was ousted on 3 July as part of the Egyptian armed forces' roadmap, which was launched days after mass nationwide protests began against the former elected president.
Morsi's supporters and opponents have frequently faced off since his overthrow, leading to at least 200 dead and hundreds injured in the past few weeks.
Both camps have used firearms against one other, among other weapons, on numerous occasions.
The health ministry has yet to issue a report on injuries in this incident.
