At least 37 people including foreigners have been killed in an attack on a hotel in the Tunisian beach resort of Sousse, an interior ministry spokesperson said on Friday.
Details of the attack, which a local security source at the scene and radio reported was on the Imperial Marhaba hotel, were still emerging.
The body of one gunman lay at the scene with a Kalashnikov assault rifle after he was shot in an exchange of gunfire with police, the source said.
Sousse is one of Tunisia's most popular beach resorts, drawing visitors from Europe and neighbouring North African countries.
Tunisia has been on high alert since March when Islamist militant gunmen attacked the Bardo museum in Tunis, killing a group of foreign tourists in one of the worst attacks in a decade in the North African country.
