(CNN) Two tourists were killed and four others were injured Friday in a knife attack in Egypt's Red Sea resort town of Hurghada, Egyptian state-run news agency Al-Ahram reported.

Al-Ahram initially reported that the two slain tourists were Ukrainian. However, Ukrainian Foreign Ministry official Vasyl Kyrylych told CNN that this is not the case, citing what police told his country's embassy in Egypt. As of Friday night, no further details on the victims were available.

An assailant with a knife attacked six female tourists in a beach resort area of the town, Egypt's Interior Ministry said earlier about the incident.

A suspect has been arrested, and victims were taken to a hospital, the ministry said.

Investigators believe the attacker swam from a public beach, according to the ministry.
