Nouakchott: Three Mauritania have been jailed for between five and 10 years for links with the Islamic State group.
A court in the capital Nouakchott handed down the sentences late on Tuesday after a trial lasting just one day, the source said on condition of anonymity.
The men, whose ages were not specified, were convicted of "belonging to a terrorist organisation and possession of terrorist propaganda" following their arrest in October last year.
They denied the charge but the court was shown a video in which all three pledged allegiance to IS.
The group ringleader Sidi Mohamed ould Ali Lasfar received 10 years, while the other two received five and seven year sentences.
The convictions were the first for links to IS in Mauritania, although the country is holding 30 prisoners for involvement with Al-Qaeda, 10 of them on death row.
