Two Britons were among dozens of tourists on a luxury Kenyan safari holiday to be airlifted to safety after their camp was hit by flash flooding. The Royal Air Force and U.K army, who train in the area, joined the rescue. Hours of torrential rain caused the Uaso Nyiro River to burst its banks, submerging luxury lodges. The floods also destroyed an important elephant research centre. Safari tour guide Steve Lekango said at least 17 tourists, including Britons, Germans and Americans, were rescued by helicopter after bridges were destroyed by the deluge.<br/>
