A resident told the French news agency AFP that 15 people were killed at the ceremony in Tillabéri region, which borders Mali and Burkina Faso, before moving elsewhere and killing seven others.

"While people celebrated a baptism ceremony, gunmen opened fire, sowing death and terror," local civil rights activist Maikoul Zodi said on social media.Niger's military government has struggled to contain jihadist violence in the region, carried out by groups linked to al-Qaeda and Islamic State. The AFP news agency also cited local media outlet Elmaestro TV as reporting a "gruesome death toll of 22 innocent people cowardly killed without reason or justification". Niger's authorities have confirmed there was an attack in the area but have not given any casualty figures.

Last week, Human Rights Watch said jihadist groups had increased attacks in the country since March, summarily killing over 127 villagers and Muslim worshippers. Dozens of homes have been looted and burned over the same period, it said. The group blamed authorities for not adequately responding to warnings of attacks and ignoring calls for help by villagers. Last Wednesday, 14 Nigerien soldiers were killed in an ambush in the Tillabéri region, a figure that the army announced in its weekly bulletin on Saturday.

The army said one of its units was deployed following reports of a cattle theft by armed men, but the operation turned out to be "an ambush". It is often difficult to independently verify the real numbers of casualties in such attacks due to access restrictions and the fear of reprisals among witnesses and local media. (BBC)
