Gunman 'had help' from others, say officials

The gunman who killed 38 at a beach near the Tunisian city of Sousse had help in carrying out the attack, officials say. Interior ministry spokesman Mohamed Ali Aroui said authorities were "sure" that Seifeddine Rezgui had had accomplices.

The government has announced increased security measures after the attack claimed by Islamic State (IS). Tunisian investigators believe the suspected accomplices provided the Kalashnikov assault rifle to Rezgui and helped him get to the scene, Mr Ali Aroui said.

He added that police were questioning Rezgui's father and three roommates, although he did not say any of them were suspected of involvement in the attack. Neighbours and relatives in Rezgui's hometown of Gaafour have been telling journalists at their shock over his actions.
