Masked assailants threw explosive devices a church in the city of Malawi in Upper Egypt’s Minya governorate on Friday.

Eyewitnesses told Ahram Arabic that helicopters have been circling the area where explosions took place, and that armed assailants fled after being chased by police. They also reported hearing gunfire.

Clashes have been taking place over the last two days, following the violent dispersal of two large protest camps in Cairo by supporters of ousted president Mohamed Morsi on Wednesday.

More than 32 churches have been burned or looted in the ongoing violence, with many other Christian-owned properties targeted. A large number of the attacks were in Minya, a region with a history of sectarian tensions. On Thursday, mobs attacked and looted Malawi’s museum and damaged the town’s police station.

On Friday protestors took to the street nationwide in what they dubbed the “Friday of anger” to condemn the bloody dispersal of the sit-ins.
