Security 'failures' noted in attack

More than 20 suspects arrested in connection with museum shooting

Tunisian President Beji Caid Essebsi said security "failures" had helped facilitate the Islamic State group's deadly attack on the country's national museum on Wednesday that killed 23 people, 20 of them foreign tourists.

"There were failures," which meant that "the police and intelligence were not systematic enough to ensure the safety of the museum", Essebsi told the Paris Match weekly in an interview published on Saturday.
