A military convoy struck a roadside bomb in the northwest of the conflict-wracked Central African Republic, leaving two police officers and three Russian paramilitaries dead, the government said Sunday.
Tensions have been high in the country of 4.7 million since a December presidential election, although a recent surge in violence is just the latest in a civil war that has lasted since the ouster of President Francois Bozize in 2013.
"Three Russian allies and two Central African police officers were killed," government spokesman Ange Maxime Kazagui told AFP, while U.N. sources said the attack Thursday also wounded five members of the Central African security forces.
They said the convoy was blown up on the road between Berberati and Bouar, more than 400 kilometers (250 miles) from the capital Bangui.
A Russian helicopter was sent to the scene to recover the victims' bodies and the wounded, the sources said.
Moscow, which wields significant influence in the poor African nation, has since 2018 maintained a large contingent of "instructors" to train the Central African army.
They were joined in December by hundreds more Russian paramilitaries, along with Rwandan troops, who were key in helping President Faustin Archange Touadera's army to thwart a rebellion.
Bangui referred to the Russian "military" in a bilateral defense accord, before Moscow corrected it by referring to them as "instructors."
Numerous witnesses and NGOs say the instructors are in fact paramilitaries from the Wagner Group, a shadowy private military company that is actively participating in the fight against CAR rebels, alongside Rwandan special forces and U.N. peacekeepers.
On Friday, the U.N. said 11 people were killed in less than a month by mines in the country, mainly in the northwest where some of the last bastions of rebel groups are located.
The presence of roadside bombs and mines is a rather new phenomenon in the country, despite years of conflict.
Most of the territory of the perennially unstable former French colony is divided among numerous armed bands.
