A United Nations report accuses Eritrea of planning a car bomb attack at an African Union summit in Ethiopia.
The accusations, which Eritrea denies, are contained in a report published by a UN team monitoring sanctions against Somalia.
The report outlines the details of the plan to attack the headquarters of the African Union in Addis Ababa at a summit in January 2011, with a car bomb. It says the aim was to ''kill many people''.
It also states that Asmara's spies are active in Uganda, South Sudan, Kenya and Somalia, posing a threat to regional peace and security.
''The report is absurd. We have never been involved in any acts of terrorism,'' said Eritrean ambassador to the UN, Araya Desta, in an interview with a BBC radio programme, Focus on Africa.
