CAIRO - Scores of angry Copts Friday continued to sit in inside a cathederal in Cairo to protest at the disappearance of a Christian woman in southern Egypt. They have vowed not to leave the church until they take the woman with them back to her homeland. The woman, a wife of a priest, has gone missing since Sunday. The protesters claimed that the woman, identified as Kamelia Shehata, had been abducted and some of them accused police of involvement. "We will remain on a sit-in here until the priest's wife returns," said Wesa Sobhi, a bishop from Upper Egypt. "The number of protesters is rising." Sobhi denied that Kamelia has converted to Islam. "The wife of the priest is a symbol of Christianity," he said. Tensions between Egypt's Muslims and Christian minority have occasionally erupted due to disputes over conversions and sites of worship. Christians account for around 10 per cent of Egypt's 80 million population.
