Gunmen launch attacks in Burkina Faso's capital, killing 7 and injuring dozens
Country targeted in the past by jihadist groups operating across Sahel region
Gunmen in Burkina Faso's capital killed seven people and wounded some 50 others in a co-ordinated assault on the army headquarters and French Embassy.
There was no immediate claim of responsibility for the attack, which is the third major assault on Ouagadougou in just over two years.
Previous attacks were conducted by allies of al-Qaeda in reprisal for Burkina Faso's participation in a regional fight against Islamist militants.
Speaking on state television, government spokesperson Remi Dandjinou said the unidentified gunmen killed five Burkinabe soldiers and wounded around 50 others at the military headquarters. Two members of Burkina Faso's paramilitary gendarmes were killed defending the embassy, he said.
A government statement said four gunmen were "neutralized" at the French Embassy. The defence minister said three assailants were killed at the army headquarters.
Police said one member of the group, who had attempted to flee near the city's main market, was being surrounded by security forces.
Witnesses said masked gunmen attacked the downtown army headquarters at around 10 a.m. local time.
"I saw people with sacks on their backs attack the guard. Then I heard the explosion," Kader Sanou told Reuters. "I saw soldiers flee the army headquarters building running."
A French diplomatic source said that no French nationals were killed in the attacks.
The explosion inside the headquarters shook surrounding buildings, set the compound on fire and sent up a thick column of black smoke.
Panicked residents fled the city centre on foot or motorbikes as dozens of Burkina Faso special forces and armoured vehicles took up positions in the area.
A Reuters reporter saw an ambulance entering the army compound.
Around two kilometres away, the French Embassy also came under attack. Police also took up positions near the offices of the prime minister where gunfire was also reported.
"Burkinabe security forces are mobilized against the attackers with the support of security forces at our embassy," said French Foreign Minister Jean-Yves Le Drian in a statement.
An aide to Le Drian later said the diplomatic compound and Ouagadougou's French cultural institute, which the embassy had earlier said was involved in the attack, were no longer in danger.
Police took up positions near the offices of the prime minister where gunfire was also reported.
A Reuters reporter said gunfire had largely ceased by noon.
The French targets attacked are symbolic given that French President Emmanuel Macron chose to outline his Africa strategy, including the fight against militants, in Ouagadougou in November.
Burkina Faso is a former French colony and, like several others countries in West Africa and Central Africa, retains close security and trade links with Paris. The landlocked country of around 19 million exports cotton and gold.
Jean-Marc Châtaigner, France's ambassador to West Africa's Sahel region, tweeted: "Terrorist attack this morning in Ouagadougou, Burkina Faso: solidarity with colleagues and Burkinabe friends." He urged people to avoid the city centre.
Islamist militants have stepped up attacks in major cities in West Africa the last few years, including deadly assaults in Mali, Burkina Faso, Ivory Coast and Niger.
Suspected jihadists killed at least 18 people last August during a raid on a restaurant in Ouagadougou, and militants have targeted Burkinabe security forces along its remote northern border region with Mali.
Al-Qaeda in the Islamic Maghreb (AQIM) claimed responsibility for an attack on a restaurant and hotel in Ouagadougou in January 2016 in which 30 people were killed.
Five countries — Burkina Faso, Niger, Chad, Mali and Mauritania — launched a new task force last year to tackle Islamist militants in the arid Sahel region, to which international donors have committed $500 million US.
France which has some 4,000 troops in the region as part of a counter-terrorism force, has bemoaned that the militants have scored military and symbolic victories in West Africa while the G5 force has struggled to win financing and become operational.
