Egypt state media says a bomb has gone off in a church in the Nile Delta, causing casualties.

The MENA news agency attributed the report to unnamed Interior Ministry officials, who provided no further details.

The explosion took place in the town of Tanta as Coptic Christians were marking Palm Sunday. Christians make up around 10 percent of Egypt's population and have repeatedly been targeted by Islamic extremists.
