An Aswat Masriya eyewitness said on Friday that clashes were renewed this afternoon as some protesters showered the Mar Girgis Church in Kom Ombo, Aswan with petrol bombs and stones.
The protesters accused the church of kidnapping a Muslim woman to convert her into Christianity.
The witness said that the security forces responded by throwing teargas bombs at the protesters.
He added that the allegedly kidnapped woman is called Huda Tuni, aged 37.
Hundreds gathered in front of the church on Thursday after rumors spread that the woman was kidnapped to be forced into converting.
The church and the security forces denied that the girl is kidnapped for conversion, saying that it is a standard case of disappearance.
Archbishop Yohana Rizk stressed that finding the missing woman is the responsibility of both Muslims and Christians.
