The militant group said in a statement carried by its news agency Amaq that a suicide bomber whom it identified as Abu Abdallah al-Masri had detonated his explosive belt inside the church.
"Every infidel and apostate in Egypt and everywhere should know that our war ... continues," it said.
The Interior Ministry identified the bomber on Monday as 22-year-old student Mahmoud Shafik Mohammed Mostafa, and said he was a supporter of the banned Muslim Brotherhood political movement who had joined a militant cell while on the run from police.
