One of Mali's top jihadist groups says a French hostage it kidnapped in November 2012 is dead.
The Movement for Oneness and Jihad in West Africa (MUJAO), a splinter group of al-Qaeda's regional branch, told AFP Gilberto Rodrigues Leal "is dead, because France is our enemy".
Yoro Abdoul Salam, a spokesman for the group, gave no details on the date or circumstances of Rodrigues Leal's death during a brief telephone exchange.
Pressed for evidence in the absence of any pictures or video footage of Rodrigues Leal's body, he said that "in the name of Allah, he is dead", before hanging up.
Last week another MUJAO official warned of "the end of life" for the 62-year-old hostage in a short message from a Malian mobile phone sent to AFP.

"France will do everything to find the truth about what happened to Gilberto Rodrigues Leal and will not let it go unpunished," French President Francois Hollande said in a statement.
"There is every reason to believe that our compatriot died several weeks ago because of the conditions in which he was being held."
French foreign ministry spokesman Romain Nadal said the government had feared for Rodrigues Leal's safety for months and had informed his family that he may be dead in December 2013.
"We condemn in the strongest terms the actions of this terrorist group," he said in a statement.
The announcement came two days after French Foreign Minister Laurent Fabius said he was "extremely worried" about the safety of the 62-year-old.
"We haven't had any news for a long time. We are in contact with the family but we are extremely worried," he said.
Rodrigues Leal was kidnapped on November 20, 2012 by armed men near the western town of Kayes as he was driving a camper van from Mauritania.
MUJAO is one of several Islamist groups that occupied the vast desert north of Mali along with Tuareg separatist rebels in 2012, in the wake of a military coup.
The Islamists later routed the Tuareg and began an advance on Bamako that led to a military intervention by former colonial power France in January 2013.
