Dakar - A United Nations children's agency staffer and five other education workers have been killed in an attack in Central African Republic, the UN agency said on Wednesday.
The team came under attack Sunday while traveling near Markounda, a remote northwestern area near the border with Chad.
"We strongly condemn this senseless act against aid workers who were there to improve the lives of the most vulnerable populations," said Unicef's West and Central Africa regional director, Marie-Pierre Poirier.
The Unicef said it has no further details.
Central African Republic has faced deadly interreligious and intercommunal fighting since 2013, when predominantly Muslim Seleka rebels seized power in the capital, Bangui. Mostly Christian anti-Balaka militias fought back, resulting in thousands of people killed and hundreds of thousands displaced.
The impoverished country saw a period of relative peace in late 2015 and 2016 but violence has intensified and spread in the past year.
In August, clashes between a militia and a self-defense group in the southeast killed 30 civilians, including six Red Cross volunteers.
The violence has blocked many humanitarian workers from doing their work.
