Third Tunisian museum gunman 'on the run'

Tunisia's president has confirmed reports that there was a third gunman involved in the Tunis museum attack that killed 23 people last week.

President Beji Caid Essebsi said that the third attacker was on the run but insisted he "won't get far".

CCTV footage of the attack showed two gunman at the museum who were killed during the battle with security forces but Essebsi said another suspect had also been caught on camera.

"For sure there were three because they have been identified and filmed on surveillance cameras," Essebsi said in a televised interview with Europe 1 radio, iTELE and Le Monde newspaper.

"There are two who were executed and one who is on the run somewhere. But in any case, he won't get far," he added.

The president also said on French TV that a monument would be built to commemorate the dead.
