( CNN) Egyptians of different religions rallied together on Sunday in defiance of ISIS, after the group claimed responsibility for two Coptic Christian church bombings hundreds of miles apart. The onslaughts left at the least 43 dead and dozens more injured, amid grim scenes of hollowed-out churches, with body parts and blood scattered among the debris.

Outraged Egyptians posted messages of solidarity with members of the embattled religion minority on social media, use a hashtag mentioning “your terrorism brings us together.”

On Sunday night, objectors met outside Alexandria’s St. Mark’s Coptic Orthodox Cathedral to condemn the attacks, criticize the government’s response to mistreatment of Copts and demand the resignation of the interior minister.
