At least 27 people, mostly foreigners, have been killed in an attack on a beach near two tourist hotels in the Tunisian resort town of Sousse, according to the interior ministry, the BBC reports.
Officials say one gunman has been shot dead and another is being pursued.
Sousse is a popular tourist destination.
Tunisia has been on high alert since March when militants killed 22 people, mainly foreign tourists, in an attack on a museum in the capital Tunis.
