Mauritanian President Mohamed Ould Abdel Aziz recovers at the Ksar Military Hospital in Noukchott, Mauritania, on Sunday before evacuation to France for further treatment for a gunshot wound.

NOUAKCHOTT, Mauritania -- The president of coup-prone Mauritania was flown to France for medical treatment on Sunday after officials said the Western ally against al-Qaida was accidentally shot by "jumpy" soldiers.

The shooting late Saturday set the northwest African country on edge and President Mohamed Ould Abdel Aziz appealed to Mauritanians to keep calm in a televised message from his hospital bed.

Although Mauritania has been stable politically since Abdel Aziz seized power in 2008, it lies on the fringes of the Sahara Desert where Islamist gunmen hold increasing sway.

"I want to reassure everyone about my state of health after this incident committed by error," Abdel Aziz said from his bed. "Thanks to God, I am doing well."

He was covered in a sheet up to his neck and the extent of his wounds was not clear. Medical sources told Reuters he had been shot in the abdomen, though the government announced he had been "lightly wounded."

The president was flown to former colonial power France on Sunday morning after undergoing an initial operation in a military hospital in the Mauritanian capital Nouakchott.

The French defense ministry confirmed Aziz would receive treatment at the Percy-Clamart military hospital on the outskirts of Paris.

'Jumpy' soldiers open fire on convoy
Abdel Aziz was wounded late Saturday when soldiers opened fire on his car about 25 miles from Nouakchott, the government said. He was driving through the town of Toueila, in an area where he owns a ranch.

Officials did not say what had happened to the soldiers who had opened fire on the convoy.

"It was a unit of the Mauritanian army, a mobile control unit. They weren't aware of his passage," Foreign Minister Hamadi Ould Hamadi told Reuters Sunday.

A Mauritanian diplomatic source told Britain’s Guardian newspaper that "jumpy" soldiers mistook Abdel Aziz for a security threat.

"Security forces have been on high alert for the last six days, jumpy, and were concerned that something might happen. Obviously this incident is very unfortunate," the Guardian quoted the source as saying.

Soldiers 'live with their fingers on the trigger'
The streets of the capital were initially deserted as rumors spread of a military coup or of an assassination attempt against the president by Islamic militants.

A prominent Mauritanian journalist, speaking to The New York Times, said the official account of the shooting was likely accurate.

“The accidental explanation is the likeliest. The president himself is saying it. And the soldiers are very nervous. They live with their fingers on the trigger,” Isselmou Ould Moustapha, editor of the newspaper Tahalil, told the Times.

But as reports of the incident spread, hundreds of residents converged on the military hospital where Abdel Aziz was being treated to show their support for the president.

Life had largely returned to normal on Sunday, with shops opening and cars returning to the streets. No additional police or military presence was visible.

Islamist menace
As the head of one of West Africa's more effective armies, Abel Aziz ordered military strikes against Islamist bases in neighboring Mali in 2010 and 2011, provoking threats of revenge from the al-Qaida-linked fighters.

Those Islamist groups now occupy the northern two-thirds of Mali after hijacking a Tuareg rebellion there earlier this year and launching a rapid offensive in the wake of a military coup in the capital Bamako.

The events in Mali have pushed thousands of refugees into Mauritania, placing a strain on resources and raising tensions along the two countries' long, desert border.

While security, including more military patrols, has been beefed up to combat the threat of foreign Islamists, Abdel Aziz often travels with only a light armed escort.

"Security is too loose. That should be revised. We all must pay attention to roadblocks, patrols and military zones, especially in this time when the Sahel region is unstable," said Mohamed Fall Ould Oumer, of the weekly newspaper La Tribune.

"If the president had died it could have been a threat to stability within the country and in the region," he said.

Abdel Aziz was elected in 2009 after seizing power a year earlier in a coup that cut short the rule of Mauritania's first democratically elected president.

Split between black and Arab Africa, Mauritania is bigger than Turkey but has only 3.5 million people. The largely desert country produces oil from wells offshore. Its other main export industries are mining and fishing.
