AMMONNEWS - At least 25 people were killed and dozens injured following a bombing inside a church in Egypt's Tanta, north of Cairo, Al Arabiya News Channel reported on Sunday.
The blast struck the Mar Girgis Coptic Church in the Nile Delta City of Tanta as the Coptic Christian community marked Palm Sunday, one of the holiest days of the Christian calendar. It marks the triumphant entrance of Jesus to the city of Jerusalem.
There was no immediate claim of responsibility and the cause of the blast was not yet known.
Al Azhar, Egypt's leading authority has condemned the attack, describing the blast as a "crime against all Egyptians."
Provincial governor Ahmad Deif told state television that at least 42 people were wounded and that the explosion occurred inside the church.
"Either a bomb was planted or someone blew himself up," Deif said, adding that security forces had searched the church and surrounding areas for additional explosive devices.
