“The Secretary-General trusts that the Nigerien authorities will spare no effort in identifying and swiftly bringing the perpetrators of this heinous act to justice while enhancing the protection of civilians,” the statement said.
Mr. Guterres also reaffirmed the solidarity and support of the United Nations to the Government and people of Niger in their fight against terrorism, violent extremism and organized crime.
President of the UN General Assembly Volkan Bozkir also denounced the attacks.
The attacks, targeting the villages of Tchombangou and Zaroumbareye, in Tillabéri region, are said to be one of the deadliest in the country badly affected by Boko Haram violence. The villages are located about 120 kilometres (75 miles) from capital Niamey.
According to local reports, several gunmen, riding motorcycles, split into two groups and attacked the villages simultaneously. Up to 70 people were killed in Tchombangou and 30 in Zaroumbareye. At least 75 people are also said to have been wounded.
Last month, at least 28 people were killed and hundreds more wounded in an attack, later claimed by the Boko Haram terrorist group, in Niger’s southeastern Diffa region.
