Tunisian presidency announced Wednesday it will close its border points with Libya for 15 days after the Islamic State (ISIS) has claimed responsibility for bombing a bus carrying members of Tunisia's presidential guard which left fifteen people killed, Al-Bawaba News reported. In a statement, Tunisian President Beji Caid Essebsi gave instructions to close the borders with Libya because the security authorities suspected that the suicide bomber had come from Libya or that the explosive belt had been brought from Libya, which is plagued by many terrorist groups.
