An IS-affiliated local group claimed responsibility. Apparently they hit a mosque frequented by Sufis in northern Sinai, roughly between the Nile delta and Gaza, employing pretty sophisticated tactics to ensure maximum casualties. Those Sufis really had it coming, being Sufis and all that.
Gotta say, nothing garners you international sympathy for your tribe and ensures lasting prosperity more than bombing indigenous minorities or tourists. I wonder who's next, is it Copts, Jews, infidel tourists, Copts, or policemen? Either way, I'm sure there will be some apologist who will tell us it's all the fault of someone else (The WestTM? Secularism? Israel?), and those poor oppressed tribesmen have no choice other than murdering everyone who isn't from their tribe.
Update: now more than 300 dead, which makes it the bloodiest attack in modern Egyptian history, I believe.
