The Tunisian gunman who carried out the hotel attack last Friday that killed 38 people, mostly British tourists, trained in a jihadist camp in Libya at the end of last year, Tunisian prime minister's spokesman Dafer Neji said on Tuesday.
Neji said investigations showed Saif Rezgui, a student who was shot by police during Friday's attack on the resort town of Sousse, was in Libya at the same time as the two Tunisian gunmen who attacked the Tunis Bardo museum in March.
The attack by a gunman on the Imperial Marhaba beach hotel in the popular resort town of Sousse came just months after militants attacked the Bardo museum in Tunis, killing 21 people, and delivering a blow to the country's vital tourism industry.
"The attack had a great impact on the economy, the losses will be large," Tourism Minister Salma Loumi told reporters late on Monday, giving a preliminary estimate from the Sousse attack.
The North African country earned $1.95 billion in revenues from tourism last year. The sector makes up seven percent of its gross domestic product and is a major source of foreign currency and employment for Tunisia.
Loumi said the government planned to end a visitors' tax and also to review debt relief for hotel operators as ways to help sustain the industry.
Authorities have arrested suspects tied to the attacker, but have given few details.
