A grenade thrown at French soldiers wounded three civilians in Ouagadougou shortly before the arrival of French President Emmanuel Macron, Radio France International reported.
The grenade was thrown hours before Macron was due to speak to a university audience at Ouagadougou, the radio station, citing security sources, said.
Two hooded individuals threw the grenade from a motorbike before fleeing, the radio said. There was no immediate comment on the incident from Macron’s office.
Macron and German Chancellor Angela Merkel are due to address an EU-Africa summit in Abidjan this week, focusing on education, investment in youth and economic development to prevent refugees and economic migrants from attempting the treacherous journey across the Mediterranean.
