About 40% of Burkina Faso<\/a> is under the control of groups linked to al-Qaeda and Islamic State operating in West Africa’s Sahel region.<\/p>\nThe attacks, in which thousands of people have been killed and millions displaced, have continued despite promises by the country’s military leaders to deal with the insurgency.<\/p>\n
Ahead of the release of the HRW findings on Monday, there were reports of more militant attacks over the weekend with dozens of military and civilian casualties.<\/p>\n
The BBC has not been able to confirm these reports and the authorities do not routinely comment on reported jihadist attacks.<\/p>\n
The BBC has approached the Burkina Faso government for comment on the HRW report.<\/p>\n
Last year, the government described as “baseless” another HRW report that had accused soldiers of a “massacre” in which 223 villagers were killed.<\/p>\n
It also said that any allegations of human rights abuses committed “in the fight against terrorism” were systematically investigated.<\/p>\n
The rights group says it interviewed witnesses, militia members, journalists and the civil society and analysed videos shared on social media to make the findings regarding the army’s involvement in the March killings.<\/p>\n
HRW previously said the army was “implicated” in the killings, based on videos that were being shared online showing dozens of dead and injured people, although the findings were not definitive.<\/p>\n
It now says further research has “uncovered that Burkina Faso’s military was responsible for these mass killings of Fulani civilians”.<\/p>\n
It adds that least 100 more civilians were killed last month in reprisal attacks by jihadist groups against those seen as helping the military.<\/p>\n
“Mass killings of civilians by government security forces, militias, and Islamist armed groups amount to war crimes and other possible atrocity crimes,” it says.<\/p>\n
The rights group has urged the government to investigate and prosecute all those responsible for the crimes.<\/p>\n
This came as junta leader Capt Ibrahim Traor\u00e9 returned from Moscow after a Friday meeting with Vladimir Putin on cooperation and security in the Sahel.<\/p>\n
Since the military seized power, Burkina Faso has turned away from colonial power France and towards Russia for help in tacking the Islamist insurgency.<\/p>\n
