Seifeddine Rezgui, the Tunisian Islamist mass-murderer who killed 38 innocent people at the beach resort of Sousse, is thought to have been trained in Libya, security sources say.
A senior official at the Tunisian interior ministry told the Associated Press that Rezgui had been in Libya in January, the same time as two men who attacked a Tunisian museum in March.
"The attacker trained in Libya with weapons at the same period as the Bardo [museum] attackers," Rafik Chelli from the interior ministry told AP.
Mr Rafik Chelli said further that Rezgui had travelled to the Libyan town of Sabratha at the same time as the Bardo attackers. "He crossed the borders secretly," Mr Rafik Chielli told AP.
IS has a significant presence in Libya, Tunisia's eastern neighbour, and is thought to control the major towns of Derna and Sirte.
The Tunisian authorities have released photos of two suspects, Bin Abdallah and Rafkhe Talari - friends of Rezgui that the police have yet to locate.
The media reports that Rezgui, 23, was radicalised while studying engineering....But fact remains that no one cares about what or when the man became a monster. Fact is he killed in the name of a religion that he was thought this way.
The Tunisian authorities have already arrested several suspected accomplices.
The Islamic State group (IS) has claimed the attack as its own. IS also said it was behind the Bardo museum attack in Tunis that left 22 people dead.
At last but not least
Tunisian President Beji Caid Essebsi has admitted that the security services were not prepared for an attack of this kind. He said extra security had been put in place at other locations during the Islamic holy month of Ramadan, but nobody had expected beaches to be a target.
SDR would like to add the following: If you need to travel for holiday, then please think twice if you wish to travel to any Islamic nation. Fact is that the chances of becomming attacked has in the last ten years proven that its generally unsafe. It doesn't pay to take risks be it Turkey, Egypt or Bali Saudi Arabia or any other nation like them your safety is not as good as in Reykjavik Iceland or even Cuba.
