WASHINGTON DC — Buckingham Palace is reviewing security arrangements for King Charles's state visit to the United States after gunshots were fired at the White House Correspondents' Dinner in Washington on Saturday night. The palace said the king was being kept fully informed of developments and was relieved to hear that the president, first lady and all guests were unharmed.

"A number of discussions will be taking place throughout the day to discuss with US colleagues and our respective teams to what degree the events of Saturday evening may or may not impact on the operational planning for the visit," Buckingham Palace said. Guests at the dinner hid under tables when gunshots were heard, and the Secret Service evacuated the president and other members of his administration during the incident.

An officer wearing a bulletproof vest was shot and taken to hospital. No one was killed. The suspect, 31-year-old Cole Tomas Allen of Torrance, California, was carrying a shotgun and a handgun. Allen was arrested on suspicion of assaulting an officer with a dangerous weapon and taken into police custody.

Darren Jones, chief secretary to the prime minister, said the U.S. and U.K. were working closely to ensure appropriate security arrangements were in place for the visit, with discussions about the king's security scheduled for Sunday. "The government and the palace take the security of his majesty very seriously, and there were already extensive discussions taking place, which will continue over the coming days," he said. Jones added: "There'll be appropriate security in place in relation to the risk."

The king is due to visit Virginia, New York and Washington during a four-day trip beginning on Monday to mark the 250th anniversary of U.S. independence. He will meet the president privately and take part in a state banquet held for him and Queen Camilla. Charles will also take part in a 9/11 wreath-laying ceremony with the mayor of New York, Zohran Mamdani, in memory of the 67 British people killed in the 2001 attack.
