Thousands of Norwegians, official guests and the royal houses of Europe arrived Wednesday to pay their last respects to Norway's King Olav V in a funeral service to mark the passing of the world's oldest monarch.

The event was to bring together the largest gathering of VIPs since the start of the gulf war, and security in the Norwegian capital was tight, with anti-terrorist units discreetly positioned in and around Oslo and airports.Among those scheduled to attend were monarchs from Belgium, Holland, Denmark, Sweden and Spain; crown princes from Britain and Japan; presidents from Yugoslavia, Ireland, Czechoslovakia, Germany and Finland; and vice presidents from the United States and the Soviet Union.
