British royalty Prince William and Kate Middleton went to the French embassy in Knightsbridge London to pay tribute to the victims of the morbid Paris attacks.

According to Daily Mail UK, the Duke and Duchess of Cambridge looked gloomy in black as they filled in a book of condolences, to pay respects to the memory of at least 129 victims of the shootings and suicide bombings that disrupted the peace of the French capital.  

Prince William wrote, "To all those who have died and were injured in the heartless attacks in Paris, and to all the people in France: Nos plus sincères condoléances [our deepest condolences]," He went on and signed his name after the message. Kate had the chance to pause and read her husband's message to the victims of the terrorist killings, and then she signed her name under William's.

The royal couple was able to speak with French Ambassador Sylvie Bermann. The duchess asked if she knew anyone who had died of the unspeakable tragedy in Paris. And as they were about to leave, the duke allegedly said that the attack was 'truly dreadful.'

Many people continue to visit the ambassador's residence to show their support and extend their condolences. On the same day, Prime Minister David Cameron was also present at the Kensington Palace Gardens to sign the book and pay his tribute. On his message, he referenced to France's motto: 'liberte, egalite, fraternite,' which means 'freedom, equality and brotherhood.'

The shootings and bombings happened in different places in France, including the Bataclan concert hall, last November 13. According to E! at least 129 people died, and more than 350 people are currently recovering from wounds and injuries.

French President Francois Hollande declared a state of emergency following the attacks and stated that the France is at war with ISIS because they attacked the country's values, their youth, and their way of life.
