Egyptian authorities arrested three suspects, Friday, in the Christmas Eve attack on a church that left six church-goers and a Muslim guard dead.
Three gunmen drove by the Virgin Mary Church in the town of Nag Hamadi on Christmas Eve and randomly opened fire into a crowd walking out, local officials said. Congregants had just finished Midnight Mass in recognition of Coptic Christmas.
Police say all three suspects have criminal records.
Meanwhile, order has been restored Friday after thousands of Christians rioted following the attack.
A recent report by Amnesty International says sectarian attacks on Christians increased in 2008. Christians make up about 10 percent of Egypt's mostly Muslim population.
