ROUGH CUT (No reporter narration) STORY: Britains's Duke and Duchess of Cambridge signed a book of condolences in memory of the victims of last week's Paris attacks at the French Embassy in London on Tuesday (November 17). Prince William and his wife, Kate were met by the French Ambassador to the UK Sylvie Bermann before the two added their messages in the book. World leaders responded to the deadly attacks in Paris with defiant pledges of solidarity and Europe tightened security after Islamic State said it was behind Friday's (November 13) assault by gunmen and bombers that left at least 129 dead in the French capital. From Barack Obama to Vladimir Putin and across Europe and the Middle East, leaders expressed their condolences to French President Francois Hollande who said the attacks amounted to an act of war against France. After the worst bloodshed in France since the end of World War Two, European neighbors including Britain, Belgium, Switzerland, Germany and Italy increased security. France temporarily imposed border controls. London monuments including the London Eye and Tower Bridge were lit up in the red, white and blue of the French tricolour, as were Sydney's Opera House, the Taipei 101 skyscraper in Taiwan, the Senate building in Mexico City, One World Trade Center in New York, Egypt's Giza Pyramids and several other global landmarks. The deadliest attack on Europe since the 2004 Madrid bombings laid bare Islamic State's capability to strike at the heart of Europe and the difficulty of monitoring the movements of militants intent on killing. It also triggered a debate on Europe's refugee policies and the failures of Western policy in Syria.
