Egypt police foil church bombing, arrest extremist cell
The group of six included two suicide bombers, with one attacker planning to detonate himself inside a church and the other to blow himself up when police arrived, the interior ministry said.
The arrests come months after twin attacks in the Nile Delta cities of Tanta and Alexandria killed 46 Coptic worshipers and injured more than 100 others as they celebrated Palm Sunday.
Last month, masked gunmen attacked a bus carrying Coptic Christians in southern Egypt, killing at least 28 and injuring 25, a local official said.
The Islamic State group claimed responsibility for each of the attacks.
Copts make up about 10 percent of Egypt's 92 million people, but discrimination against them is entrenched in both state and society.
