Tunisia attack: Hotel worker recounts escape from beach killer

Imen Kechiche Guiga was working in her office near the the Hotel Imperial Marhaba reception when the Tunisia beach attack violence erupted. She saw the gunman and was injured by grenade fragments.

Seifeddine Rezgui, the Tunisian student who carried out the attack, also pointed his gun at her and she believed he spared her because she spoke in Arabic.

Tunisia has arrested a group of people over the massacre of 38 people, mainly tourists, by a gunman at the beach resort of Sousse on Friday, the country's interior minister has said.

The BBC's Fergal Keane reports from Sousse.
