Al-Qaeda's Mali branch has released a proof-of-life video of six foreign hostages, including elderly Australian surgeon Arthur Kenneth Elliott and Frenchwoman Sophie Petronin, US-based monitoring group SITE said.
The 16 minute, 50 second video by Nusrat al-Islam wal Muslimeen, also known as the Group to Support Islam and Muslims, was released on Telegram on Saturday, SITE said.
The other four hostages shown are South African Stephen McGown, Romanian Iulian Ghergut, Swiss missionary Beatrice Stockly and Colombian nun Gloria Cecilia Narvaez Argoti.
No group had previously claimed responsibility for kidnapping Petronin, who was abducted in late 2016 by armed men in Gao in northern Mali where she ran an organisation for malnourished children.
After the video clip showing Petronin, the narrator said she was hoping the French president would help return her to her family, SITE said.
The video was released just before President Emmanuel Macron arrived in Mali to consolidate Western backing for a regional anti-jihadist force.
In the video, the hostages are separately introduced by a narrator, who says that so far there have been no negotiations for their release.
The first shown is McGown, who was abducted in Timbuktu, northern Mali, in November 2011.
"It's a long time to be away ... Until when do you think this will come to an end? Now we're making a new video, but I don't know what to say. It's all been said in the past. It's all been said in previous videos I've made," McGown says, according to a transcript by SITE.
He is followed by Australian Elliott, in his 80s, who, along with his wife Jocelyn, was abducted in January 2015 in Djibo, Burkina Faso, where the couple had run the sole medical clinic since 1972. Jocelyn was released in February 2016.
Next in the video is Romanian mineworker Ghergut, who says he was captured in Burkina Faso on April 4, 2015.
The women are then shown, including Swiss missionary Stockly, who was kidnapped in Mali in January 2016.
Colombian nun Argoti was seized by armed men in the Mali village of Karangasso close to the Burkina Faso border in February 2017.
At the end of the undated video, while not spelling out any demands the narrator tells the hostages' families "no genuine negotiations have begun" for their release but then adds that negotiations are "still active".
In 2012, Mali's north fell under the control of jihadist groups linked to Al-Qaeda who exploited an ethnic Tuareg-led rebel uprising, though the Islamists were largely ousted by a French-led military operation in January 2013.
Since then, jihadists have continued to mount numerous attacks on civilians and the army, as well as on French and UN forces stationed there.
