Top European security officials have paid tribute to 38 people killed at a beach resort in Tunisia, as authorities announced the arrest of seven people in the hunt for accomplices of the gunman.
Tunisian interior minister Mohamed Najem Gharsalli announced the arrests of several Tunisians allegedly from a network behind attacker Seifeddine Rezgui, a 24-year-old student who was killed by police near the scene of the attack in Sousse on Friday.
Authorities say he acted alone during the rampage but had accomplices who supported him beforehand, providing him with weapons and logistical support.
Seven people were arrested in at least three different cities and are being interrogated in the capital, Tunis.
UK Home Secretary Theresa May joined French interior minister Bernard Cazeneuve, German interior minister Thomas de Maiziere and Belgian interior minister Jan Jambon joined Gharsalli on the beach in front of the Imperial Marhaba hotel in the Mediterranean resort of Sousse for the tribute to the victims.
Eighteen of the dead were confirmed as being from the UK, but it is thought this number could rise to around 30.
Standing on the sand surrounded by security officials, they at one point put their arms on each other's shoulders.
Mr Gharsalli said he and the European security leaders agreed to work together on security and economic cooperation.
The attack in the resort of Sousse was Tunisia's bloodiest ever, and the deadliest for Britain since the 7/7 bombings in 2005, in which 52 commuters died.
