This is not surprising:

Christians living in Gaza City on Monday appealed to the international community to protect them against increased attacks by Muslim extremists. Many Christians said they were prepared to leave the Gaza Strip as soon as the border crossings are reopened.

The appeal came following a series of attacks on a Christian school and church in Gaza City over the past few days.

Father Manuel Musalam, leader of the small Latin community in the Gaza Strip, said masked gunmen torched and looted the Rosary Sisters School and the Latin Church.

“The masked gunmen used rocket-propelled grenades to storm the main entrances of the school and church,” he said. “Then they destroyed almost everything inside, including the Cross, the Holy Book, computers and other equipment.”
