France's last remaining hostage, Serge Lazarevic, arrived home on Wednesday after three years at the hands of Islamist militants, to be greeted by his family and French President Francois Hollande.
The beaming 51-year-old, dressed casually in a blue hooded top, was welcomed warmly by Hollande at a military airport outside Paris before an emotional embrace with his mother and sister.
Lazarevic, sporting a closely-cropped beard, shared a joke with Hollande and the rest of his family after exiting the jet with his daughter.
"Life is good when you have freedom. I didn't know what it was like to be free. I had forgotten what it is like to be free. I will never forget it again," Lazarevic told reporters.
"Be careful, because freedom is dearer than anything. When you've been taken, when you're being abused, when you're lost, when you're close to death, you think more about life," he added.
Hollande said it was "an enormous joy" to see him back on French soil.
"Welcome back, Mr Lazarevic, we've been waiting for you for three years," said the president.
'He's doing well'
Lazarevic was taken immediately to a military hospital for check-ups before returning to the comfort of his family, according to a diplomatic source.
"The doctor gave him a check-up on the plane and he's doing well," this source said.
Lazarevic was the last of more than a dozen French citizens taken captive in recent years, with those held in Africa reaching a high of 15 last year. Four journalists held by Syrian jihadists were released earlier this year.
He was freed after intensive efforts by Niger and Mali.
There was no immediate information on how the release was secured or whether France paid a ransom.
An association, "the friends of Ghislaine Dupont", an RFI journalist killed last year in Mali, said Lazarevic had been swapped for "several hostage-takers", without revealing how they obtained their information.
Lazarevic was snatched by armed men in Mali on November 24, 2011 while on a business trip with fellow Frenchman Philippe Verdon in a kidnapping claimed by Al-Qaeda in the Islamic Maghreb (AQIM).
Verdon, who suffered from an ulcer and tachycardia - an abnormally fast heartbeat - was found shot dead last year, and those close to his family suggested he had been executed because he was weak.
Verdon's son stood alongside Lazarevic, who called him "my son" and embraced him in front of the cameras.
A Malian security source said the final stages of Lazarevic's release had taken place in the northern desert city of Kidal.
"I won't say if there was a ransom payment or liberation of prisoners," the source told AFP.
'No more French hostages'
In his three years in captivity, Lazarevic appeared in several AQIM videos, the most recent of which was in November in which he said he was gravely ill and believed his life was in danger.
The video spurred Lazarevic's daughter Diane to urge Hollande to obtain his release "as fast as possible... for Christmas."
Fears spiked for the safety of the tall Frenchman of Serbian origin after hiker Herve Gourdel was abducted in Algeria and beheaded in September by Islamic State-linked militants.
The pair, who worked in security and construction, were accused by AQIM of being French intelligence agents, something their families have denied.
Hollande thanked the authorities in Mali and Niger for their assistance in securing Lazarevic's release.
The presidency in Niamey said in a statement that the liberation was "the result of intense and continued efforts from authorities both in Niger and Mali".
"This is a joy for all the French people because there are no more French hostages in any country in the world," Hollande told reporters.
"I want to deliver a clear and simple message to our compatriots who might find themselves in a high-risk zone: make sure you don't go to places where you could be taken hostage."
One of the main armed Tuareg groups in the still-volatile region, the High Council for the Unity of Azawad (HCUA), said it had also "participated in the release" efforts.
While the details of Lazarevic's release were not given, France has repeatedly denied paying ransoms despite being accused by other Western nations of using back-channels to do so.
"France does not pay ransoms, nor does France engage in prisoner exchanges," Hollande said in September.
