Security will be heightened for the Duke and Duchess of Cambridge's royal visit to New York following protests in the city over the killing of unarmed black man Eric Garner by a police officer.
Kate and William will make their first official visit to New York during a three-day tour to America, when they will also meet President Barack Obama and his wife Michelle at the White House in Washington DC.
Thousands of protestors have taken to New York City's streets after it was revealed that the police officers who killed father of six Garner would not face criminal charges.
The royals will be accompanied by their own bodyguards from Scotland Yard, but will be given extra security by the New York Police Department.
A source close to the couple told the Daily Mail: "There is no suggestion of a direct threat to the Duke and Duchess whatsoever but the way these demonstrations are spreading is being taken into account when planning their movement."
According to Kate and William's official website, they will arrive in New York on Sunday and visit the World Bank in Washington DC, the Northside Center for Child Development in Harlem and attend an NBA Basketball game in Brooklyn on Monday. Tuesday will see the couple visit The National September 11 Memorial Museum and join the St. Andrews 600th Anniversary Dinner at the Metropolitan Museum of Art in New York.
