KEY POINTS:
A plot by terrorist group al-Qaeda to kill the Queen during a state visit to Uganda was foiled late last year by security services.
The terrorists had planned to hide inside two outside broadcast vans owned by the Ugandan Broadcasting Corporation and then set off bombs during the Queen's visit to Kampala last November.
The Queen, Prince Philip, Prince Charles and his wife Camilla all travelled to the east African nation's capital for the Commonwealth Heads of Government Meeting (CHOGM), which was attended by more than 30 world leaders.
Uganda's Minister of Internal Affairs Dr Ruhakana Rugunda said several suspected terrorists were arrested.
"We received information that a terrorist group linked to al-Qaeda, the Allied Democratic Forces, was planning to carry out terrorist activities at the Commonwealth meeting," he told the Sunday Express newspaper.
"The security services in Uganda neutralised these threats."
Security was extremely tight for the meeting, with roads in Kampala's centre closed off to local traffic and strict identity checks carried out at each of the CHOGM venues.
