Amid anger and sorrow, a state funeral was held yesterday for 22 of the victims killed when gunmen opened fire on worshippers during church mass earlier this month in Southwest Nigeria.

At least 40 people were killed, including several children, when multiple gunmen closed an entrance on a Catholic Church in the state of Ondo and opened fire. The attacked reportedly lasted about 30 minutes.

Funerals for the remaining victims killed were already held.

No one has claimed responsibility for the mass shootings, but Nigerian officials said they suspect the gunmen had ties to a group once connected to Boko Haram.

Religious attacks in Southwest Nigeria are rare. Nigerians have expressed anger and outrage over the attacks over officials’ inaction and failure to keep religious communities safe.
