Egyptian authorities have declared a three-month state of emergency after twin ISIS bombings killed 43 at two Coptic churches in the Nile Delta cities of in Tanta and Alexandria on Palm Sunday. Dozens more were injured in the attacks, which came as the churches were filled with worshippers. The first suicide blast, at Mar Girgis (St George) Church in Tanta, killed 27. Hours later, a second blast struck outside Saint Mark's church in Alexandria, where Coptic Pope Tawadros II was leading a service, killing a further 16. ISIS warned of more attacks in its statement. "The Crusaders and their apostate followers must be aware that the bill between us and them is very large, and they will be paying it like a river of blood from their sons, if God is willing," the group said in Arabic.

Human Rights Watch says tens of thousands of people have been arrested in Egypt's ongoing crackdown on dissent, and that security forces have committed harsh abuses, including torture, forced disappearances, and likely extrajudicial executions. (Ahram Online, Al Jazeera, BBC News, CNN)
