An armed Muslim mob attacked Christians in the Minya province village of Karma and stripped an elderly woman who they paraded naked on the streets.
The mob attacked seven Christian homes last week by looting and torching in a province south of the Egyptian capital.
The mob numbering 18 in all dragged the 70-year-old woman out of her home, stripped her off her clothes, beat her and insulted her for the sins of her son.
They chanted Allahu Akbar, or "God is great" as they paraded her through the streets in the south province of the Egyptian capital
Anba Makarios, Minya's top Christian cleric, told a talk show host on the private Dream TV network that rumors spread through the province that the elderly woman's son had an affair with a Muslim woman — a taboo in conservative Egypt.
Security officials have confirmed to the media that six men suspected of taking part in the violence have been arrested and are looking for 12 more.
