At least 10 people were killed this week in coordinated militant attacks on army positions in northern and eastern Burkina Faso, security sources said on Sunday.
The landlocked West African country has been battling insurgents linked to Al-Qaeda and the Islamic State group for more than a decade.
Burkina Faso has been under military rule since a 2022 coup, with the junta promising to swiftly end the violence.
Since then, authorities have largely stopped publicly reporting on militant attacks, fuelling speculation and uncertainty in the already fragile nation.
On Saturday, hundreds of attackers stormed an army unit in Titao, the capital of Loroum province in the north.
A regional security source said part of the base was destroyed but did not confirm any casualties.
Unverified claims circulating on social media suggested dozens of soldiers may have been killed.
The same day, another army base in Tandjari in the east came under attack, leaving several officers dead.
On Thursday, a separate assault targeted a military detachment in Bilanga, killing around 10 soldiers and civilian volunteers.
Much of the Bilanga post was looted, and the assailants reportedly remained in the town until the following day.
“This series of attacks is not a coincidence,” one security source said, pointing to apparent coordination between militant groups.
The violence also spilled over into neighbouring Ghana. The interior minister said a truck carrying Ghanaian tomato traders was caught up in the Titao attack.
Ghana’s embassy in Ouagadougou is working with Burkinabe authorities to determine whether any of its nationals were affected.
Despite repeated pledges by the junta to restore security, Burkina Faso remains gripped by escalating bloodshed.
According to the Armed Conflict Location and Event Data project, tens of thousands of civilians and soldiers have been killed since 2015.
More than half of those deaths have occurred in the past three years, highlighting the conflict’s rapid and deadly escalation.
