Tunis ( CNN ) Tunisian President Beji Caid Essebsi confirmed that a third person took part in last week 's Bardo museum terror attack in an interview Sunday with French TV Station iTele . `` There were for certain three terrorists , '' Essebsi said . `` There is one on the run . He will not get far . '' Previously two suspects had been identified -- Yassine Labidi and Saber Khachnaou -- though it was n't immediately clear if they were the pair killed at the museum by Tunisian security forces . He said Yassine was `` known to the security services , he was flagged and monitored , '' but not known or being followed for anything special . Authorities have arrested nine people in connection with the attack , including four directly linked to it , according to Essebsi . The development came a day after the bodies of four Italian tourists slain in the attack arrived back in Italy , an official with the Tunis Crisis Center told CNN , but 14 victims ' remains still lie in the morgue . Most of the 23 victims were foreigners , making the process of identification more complicated . Nineteen of them were tourists who 'd been on two cruise ships that docked in Tunis . French , Spanish , Italian , British , Japanese , Russian and Colombian citizens are among those to have been formally identified so far . The bodies of the Italians were met in Rome by Italian Prime Minister Matteo Renzi , who paid his respects to the victims and their families in a brief ceremony . Eleven people who were injured in the attack remained in the hospital in Tunisia on Saturday , the official at the Tunis Crisis Center said . An uncle of Yassine Labidi , Abeld Malik Labidi , told CNN on Friday that no one he knew had seen any signs of extremism in his 26-year-old nephew . But he said Yassine Labidi was one of the two gunmen killed at the museum . `` It 's true that Yassine carried out this terrorist attack , he was killed ; his head , his body , we do n't have it back , '' he said . But , he said , he believed Yassine and other young Tunisians like him were also victims of terrorism -- of the recruiters who paid them money , organized the logistics and took them to places like Syria and Libya to train as fighters . He had known his nephew well , he said . `` After the revolution of 2011 he started to pray , before he would drink beers from time to time , like a young Tunisian . He was n't extreme in any way . '' The only thing that raised questions was that Yassine had disappeared for about a month , he said . Although his nephew said he 'd gone to the Tunisian city of Sfax to work , his family now suspected he had been in Libya because of the phone numbers he called from . `` When he came back his behavior was the same : he was still himself , calm , serious . Nobody noticed anything , even the neighbors I spoke to , '' said Abeld Malik Labidi . `` He said hello to everyone , he prayed , he took his coffee , even on the day of the attack he took his coffee with his family and went to work . '' Abeld Malik Labidi said Yassine 's father , sister and brother had undergone lengthy interrogations by anti-terror police since the attack . Officers had seized his nephew 's computer and phone , as well as taking samples of his fingerprints , he said . A cousin of Yassine , who asked not to be named , told CNN that the family was shocked by what had happened . `` We are all shocked , we lost someone even if what he did was wrong , may God forgive him . Those he killed were innocent , why would you go and harm Australians or Japanese ... our Islam does n't mention about killing people , Islam has never been this , '' he said . He also said he had no idea how his cousin had been radicalized , saying he was `` a normal Tunisian guy ... but not an extremist . '' Security Minister Rafik Chelly said on Friday that the two extremists who attacked the museum got weapons training at camps in Libya . The suspects were activated from sleeper cells in Tunisia , he said . He did not say which group activated them , or with whom they trained . `` They left the country illegally last December for Libya , and they were able to train with weapons there , '' he told private broadcaster AlHiwar Ettounsi TV . Like Tunisia , Libya saw its longtime leader Moammar Gadhafi ousted during the regional wave of revolutions known as the Arab Spring . But unlike its neighbor to the west , Libya has been fraught with more instability and violence -- much of it perpetrated by Islamist militants . In an audio message posted online Thursday , ISIS claimed responsibility for Wednesday 's attack , which it said targeted `` crusaders and apostates '' with `` automatic weapons and hand grenades . '' CNN can not independently verify the legitimacy of the audio statement . That bloodshed is `` just the start , '' the ISIS message warned -- a threat that may or may not be hollow , but nonetheless adds extra urgency for Tunisian investigators .
