There have long been calls for an inquiry into Norbert Zongo's murder

The widow of a Burkinabe reporter who was murdered in 1998 has welcomed the arrest of Francois Compaore, the brother of Burkina Faso's ex-President Blaise Compaore.

Francois Compaore, 63, was reportedly arrested at an airport in Paris in connection with the death on Sunday. Norbert Zongo, the editor of newspaper L'Independant, was investigating the murder of Francois Compaore's driver at the time of his death.

His widow, Genevieve Zongo, said:

It's good news. What I say is, 'As God has begun it, so too must He end it'. This must not stop at his arrest. We want to see the follow-up. Will Francois Compaore be given over to Burkina Faso to face justice?"

Mr Zongo and three of his friends were found dead in a burnt-out car outside the capital, Ouagadougou, with bullet wounds to their bodies. His killing triggered violent protests. "The Zongo case is a sensitive topic for probing journalists and taboo in government circles," said the Committee to Protect Journalists on the 10th anniversary of Mr Zongo's death in 1998.

Francois Compaore's arrest follows an arrest warrant issued by Burkina Faso in July, on charges of "inciting murders", Mr Zongo's family is quoted as saying. He was nicknamed the "little president" because of the influence he had in his older brother's government.
