Tunis, July 2 (RHC)-- Tunisia has arrested seven people in connection with Friday’s seaside terrorist attack that left 38 people dead. The seven suspects are currently being interrogated in the capital city, Tunis, according to a source with knowledge of the investigation.

The unnamed source said four of the suspects were arrested on Monday; two in the resort town of Sousse, where the attack occurred, one in Tunis, and one in the city of Kasserine. Three others had been taken into custody a day before.

The source spoke on condition of anonymity because he was not authorized to be publicly named. Earlier, Interior Minister Mohamed Najem Gharsalli said those arrested were members of a network that was behind the assault, but provided no more details.

Gharsalli made the comment in a meeting with British, French, German and Belgian interior ministers who were in Tunisia to pay tribute to victims of the attack. The minister went on to say that Tunis was determined to fight terrorism in all its forms.

Last Friday, a Tunisian student disguised as a tourist used an MK 47 assault rifle to kill tourists at a hotel in Port El Kantaoui, near Sousse to the south of Tunis. Eyewitnesses said the gunman was mowing down screaming tourists as they ran for their lives.

Among the 38 victims there are tourists from Germany, Belgium and Portugal; however, most of the tourists killed were from the UK.
