Germany has confirmed that two tourists killed Friday after being stabbed in the Red Sea resort city of Hurghada were German nationals, a foreign ministry statement said.

Two were killed and four others injured on a beach when a man attacked them with a knife. Earlier reports Friday identified the dead tourists as Ukrainian or German, while the injured include one Czech woman and two Armenian women, a source at Hurghada General Hospital told Ahram Online Friday.

“Based on what we know now, that crime has targeted foreign tourists, a criminal act of the highest degree, which fills our hearts with feelings of sorrow, and anger,” the ministry said in a statement Saturday.

The statement added that officials of the German embassy in Cairo are currently at the scene of the attack and in contact with Egyptian authorities.

The assailant, who was arrested after the attack, had swum to the resort from a nearby public beach, according to a short statement from the Egyptian interior ministry shortly after the incident Friday.

Following the incident, the German foreign ministry released a statement condemning the attack, yet adding that the nationality of the two slain tourists had not been confirmed.
