The Duke and Duchess of Cambridge have sympathised with survivors of Paris' devastating Bataclan terrorist attack, praising their bravery and the "amazing progress" of their recovery.

The royal couple met a 25-year-old, known only as Jessica, who was shot seven times in the leg, hip and back as she dined with friends at La Belle Equipe restaurant in Paris in 2015, and Kevin, 28, a Bataclan concert-goer shot in the leg.

As the couple visited the hospital where the pair have been treated, reports came in of a terrorist incident at Paris Orly Airport, but a Kensington Palace spokesman said the royal visit was not affected.

A man was shot dead after wrestling a soldier to the ground at Orly Airport and trying to take her rifle, officials said.

No-one else in the busy terminal was hurt, but thousands of travellers were evacuated and flights were diverted to the city's other airport.

There were no signs of security - which included armed French police - being increased around the couple as they travelled around Paris.

William and Kate's two-day visit to Paris comes in the month that Prime Minister Theresa May is expected to trigger Article 50, beginning Brexit negotiations.

The couple's trip has been dubbed a Brexit charm offensive by some of the French papers, with the royals using soft diplomacy to renew ties with its European neighbour.

William's recent ''lads-only'' weekend trip, which was criticised by the press, has overshadowed the two-day visit, but he looked relaxed and at ease with his wife especially when they later posed for pictures with the famous Eiffel Tower as a backdrop.

During the hospital visit, the Duke told the Bataclan attack survivors: "We think you are very strong and very brave, you've made amazing progress."

The Duchess added she would be keeping an eye out for Jessica's work, after learning she is retraining to work in fashion.

The 25-year-old said: "At first (after the shooting) I was a bit shy and didn't want to talk about it because of all of the pain and grief.

"But now I want to say we are not only victims, we have lives, we have boyfriends, girlfriends, work. I want to speak about my friend who died to honour him, I want people to remember who he was."

She was shot on her birthday as she dined with three female friends outside the restaurant, who all survived the attack. Her friend Victor Munoz, who was inside, was killed with one shot.

"We were very lucky," she said of her friends outside. "We all got shot and we all survived."

The Duke hailed the "quick-thinking" of her boyfriend, who made a tourniquet for her leg on the scene.
