Italian police have arrested a Moroccan suspect over an attack at a Tunisian museum which left more than 20 dead.
Two gunmen killed 20 tourists at the Bardo Museum nearly in March, in one of the worst attacks in the North African country that mostly avoided violence since its 2011 uprising against autocrat Zine El-Abidine Ben Ali.
Tourists from Germany, Poland, Italy and Spain were among those killed.

Mother-of-two Sally Adey, from Shropshire, died in the shooting at the Bardo National Museum in Tunis on March 18th.
She had been on a Mediterranean cruise with her 52-year-old husband Robert, who survived the attack.
Ms Hartridge said a post-mortem examination carried out in the UK by a Home Office pathologist on March 25th had established provisional cause of death as "consistent with gunshot wounds to the abdomen and pelvis".
More than 20 people were killed in the attack, including 17 cruise ship tourists and two gunmen.
Tunisian President Beji Caid Essebsi said his country will stay "united against terrorism" in the wake of the Bardo museum massacre.
Speaking after a mass anti-terror march through the country's capital today Essebsi said: "The Tunisian people will not bow.
"We will stay united against terrorism until we wipe out this phenomenon."
The march, which was attended by tens of thousands of people, including world leaders such as France's President Hollande was organised as a sign of solidarity against Islamist militants following the terrorist attack on a Tunisian museum which killed 21 foreign tourists and a policeman.
World leaders joined thousands of demonstrators in Tunis taking part in an anti-terror march.
In attendance was President Francois Hollande, who earlier today announced that French woman Huguette Dupeu, who was injured in the attack, had died from her wounds.
Chanting "Tunisia is free! Terrorism out!" demonstrators marched to the Bardo Museum, the scene of an attack in which 21 tourists and a Tunisian died.
Hours before the march, the Tunisian Prime Minister said that the alleged leader of the attack, Lokman Abu Sakhra had been killed in an anti-terrorism operation.

Prime Minister Habib Essid said Khaled Chaieb, also known as Abou Sakhr Lokman, was killed overnight in an operation in the Gafsa region near the Algerian border.
He is believed to be a prominent militant in al Qaida's North African arm, and suspected of leading or helping lead the March 18 attack on the National Bardo Museum.
Twenty-two people, mainly foreigners, and two gunmen were killed in the attack.
An interior ministry official has said that Tunisian forces killed nine militants during a raid in a southern region as part of crackdown following the attack on the Tunis Bardo museum that targeted foreign tourists.
The operations late on Saturday in Gafsa region came hours before thousands of Tunisians were expected to join world leaders including French President Francois Hollande in a march of solaridity in Tunis.
Two gunmen killed 20 tourists at the Bardo Museum nearly two weeks ago, in one of the worst attacks in the North African country that mostly avoided violence since its 2011 uprising against autocrat Zine El-Abidine Ben Ali.
Tunisia's prime minister has sacked five leading security officials days after three gunmen attacked a Tunis museum, killing 21 people.
The ousted employees include the director of Tunisia's tourist police and the police chief for the neighbourhood around the National Bardo Museum, government spokesman Mufdi Mseddi said.
The decision was made after the prime minister, Habib Essid, visited the attack site and noted security problems, the spokesman said.
President Beji Caid Essebsi had also criticised security failings around last week's attack.
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.
More than 20 suspected militants have been arrested as part of a security crackdown carried out by Tunisian authorities since Wednesday's museum massacre.
According to reports 10 of those arrested are believed to have been directly involved in the the Bardo museum attack in which 23 people died.
Tunisia's Interior Ministry spokesman Mohamed Ali Aroui said the arrests were part of "a large-scale campaign against the extremists."
CCTV footage showing the two men behind Wednesday's deadly gun attack on a museum in Tunisia walking through the popular tourist attraction before firing their weapons has emerged.
The security camera footage, released today, shows the men calmly walking through the National Bardo museum, carrying assault rifles and bags moments before the massacre began.
One of the attackers is seen walking past the cameras wearing a baseball cap and a heavy jacket, while the other is dressed in a red hoodie and tracksuit pants. Stills of the gunmen, lying on the ground after being shot by security forces, indicate that at least one was wearing an explosive belt.
Both gunmen shown in the video were killed in a firefight with security forces.
