The Angolan army says it has killed Unita rebel leader Jonas Savimbi.
Mr Savimbi has led the rebel group's fight for power in Angola for more than 30 years.
State radio and the official news agency said Mr Savimbi had died during fighting with Angolan government forces.
There was no independent confirmation of the death.
The Angola government said Mr Savimbi had been killed in the eastern Angolan province of Moxico where the army has been waging war against Unita since October last year.
Unita has been fighting against the Luanda government since 1975.
Elections were held during a ceasefire in 1992, but Unita did not accept the results and fighting resumed.
