Berlin on Saturday said 2 women who were killed after being stabbed in an Egyptian beach resort were German nationals, confirming earlier reports."We can now sadly confirm that 2 German tourists died in the attack at Hurghada," a foreign ministry statement said.
Friday's attack in the Red Sea resort left 4 others wounded.
The attacker, who had swum ashore, was arrested and questioned.
"We don't know his motives yet, he could be crazy or perturbed -- it's too early to tell," a senior interior ministry official told AFP.
Hurghada is one of Egypt's most popular beach resorts, especially with Ukrainians and European tourists.
