HURGHADA, Egypt — The Egyptian university graduate who stabbed two German women to death at a popular Red Sea resort first sat and spoke to them in fluent German before producing a large kitchen knife and attacking them, security officials said Saturday.

Leaving them for dead, 29-year-old Abdel-Rahman Shaaban fled the scene, chased by hotel workers and security guards. He rushed into the hotel next door where he attacked and wounded four female tourists who, according to local media reports, included two Armenians, one from Ukraine and another from the Czech Republic.

“Stay back, I am not after Egyptians,” Shaaban shouted in Arabic at his pursuers, according to the officials. They eventually caught up with him, disarmed and pinned him down and later handed him over to the police. Shaaban stabbed the women in the face, neck and feet, said the officials.

No group claimed responsibility for the Friday attack, but it appeared to have been inspired by recent calls made by the local affiliate of the extremist Islamic State group on its followers to attack Egypt’s minority Christians and foreign tourists.
