Two Ukrainian tourists have been killed in mass stabbings at a hotel in the Red Sea resort of Hurghada, Egyptian medical officials say.

At least four other people were injured and a man has been arrested. The suspect is being questioned by police to determine his motives, the interior ministry said.

The attacker appears to have swum from a nearby public beach to gain access to the resort, officials say.

Hurghada is a popular Egyptian holiday resort. It is renowned for its scuba diving.

Three foreign tourists were stabbed at the same resort in January 2016 by two suspected militants from the so-called Islamic State (IS) group.
