At least 30 people, including nine soldiers, have been killed in three separate incidents in Mali.
Twenty one were killed when gunmen attacked a village in central Mali, burning houses, crops and livestock.
A group of eight soldiers also died in an ambush, while another was killed during an attack on a military camp in the Gao region.
Mali has been blighted by instability since 2012 when an Islamist rebellion broke out in the north.
The village of Ogossagou, where one of Friday’s attacks took place, is mostly home to Fulanis, a largely-Muslim ethnic group who traditionally work as herders.
Other ethnic groups in Mali – including the Dogon community – accuse the Fulani of being linked to jihadi groups operating across the Sahel region.
These accusations have fuelled a spate of inter-ethnic violence in recent years.
Last March, 160 people were killed another attack at Ogossagou, which authorities blamed it on a Dogon militia.
The attack led to several protests over perceived inaction by the government, and Mali’s prime minster at the time, Soumeylou Boubèye Maïga, later resigned.
