The Tunisian security forces have arrested a group of people accused of providing logistical and material support to Seifeddine Rezgui, the gunman who killed 38 people at a beach in Sousse on 26 June.

Those who provided support, prepared the ground for the attack and incited it will be tried in court, according to Tunisia’s Interior Minister Mohamed Gharsalli. Investigations are continuing, he was quoted as saying by the Tunisian Press Agency.

“It cannot confirm if the perpetrator of the attack had received military training in Libya.”

French, German and British ministers were in Sousse for the press conference.

It has now been confirmed that 18 of the 25 identified victims were British, with this number expected to rise to 30.

The Tunisian parliament now hopes to pass a new anti-terrorism law before 25 July. Debates on the law were interrupted in March, when armed men attacked the neighbouring Bardo Museum, killing more than 20.

The new law will give the army the right to intervene in towns in support of the security forces, which it is currently doing extralegally.

Security is now the top priority for the government, as the rising number of attacks is affecting the already struggling economy.

The country’s tourism industry is expected to collapse following the second successful attack to target foreign tourists.
