A policeman has been shot dead by two men on a motorbike on the outskirts of Sousse - the Tunisian resort which was hit by a beach massacre in June.

Three officers were targeted in the latest shooting and one was hit and died later in hospital.

The other two were also shot at but were uninjured, despite earlier claims they had been hit.

They were believed to have been attacked by a gunman armed with a Kalashnikov in the town of Ezzouhour.

A major police search is now under way for the unknown assailants after they sped away.

In June, 23-year-old jihadist gunman Seifeddine Rezgui killed 38 people, including 30 British nationals, when he opened fire on tourists as they sunbathed on a beach.

Rezgui was later shot dead by security forces. The attack was claimed by the Islamic State group.
