Gunmen killed at least 21 people, including children, in an attack on a Catholic church in southwest Nigeria on Sunday, local officials said, in violence that drew widespread international condemnation.
The bloodshed at St. Francis Catholic Church in Owo town during a service was a rare assault in Nigeria's usually safer southwest and shocked a country grown used to jihadist attacks and mass kidnappings in the north.
Richard Olatunde, spokesman for the Ondo State governor's office, told AFP that dynamite exploded inside the church before gunmen opened fire on worshippers attending the service.
Blood stains still marked the St. Francis church floor and debris lay scattered around a day after the attack.
"They did not even enter the church, they were shooting through the windows," Olatunde said, confirming a death toll of 21 people.
National Emergency Management Agency local representative Olanrewaju Kadiri said 22 people were killed, including several children, with another 40 people wounded.
Vice President Yemi Osinbajo arrived on Monday to visit some of the wounded.
Survivors described panic as worshippers fled a sudden outburst of gunshots.
"I ran back to the church and I saw my two children and we brought them here to the federal medical centre," Nzeadu Paulinus, a local resident who was away from the church when the shooting started and whose two children were wounded.
"I saw so many people who were wounded, and the dead."
The state government declared a seven-day mourning period for the victims, and ordered the national flag to be flown at half-mast in Ondo.
No group has so far claimed responsibility for the attack and the motives were not clear.
One witness told AFP he saw at least five gunmen on the church premises.
"I was passing through the area when I heard a loud explosion and gunshots inside the church," the witness, who gave his name as Abayomi, told AFP.
- Jihadists, gangs -
Nigeria's military is fighting a 12-year-long jihadist insurgency in the northeast and heavily armed criminal gangs often carry out looting raids and mass kidnappings in the northwest and north-central parts of the country.
But large-scale attacks in Nigeria's southwest are relatively rare, although kidnappings for ransom have become increasingly common.
Boko Haram jihadists in the northeast have targeted churches in the past. Nigeria's jihadist conflict has killed 40,000 and displaced two million more in the northeast.
President Muhammadu Buhari condemned Sunday's "heinous killing of worshippers" while Pope Francis offered prayers for the victims.
The UN Special Representative for West Africa and the Sahel, Mahamat Saleh Annadif, condemned what he called a "barbaric terrorist attack".
The attack came a day before the ruling APC party started primaries for its candidate in the 2023 election to replace Buhari, a former army commander who steps down after two terms in office.
Security will be a major challenge for whoever wins the race to govern Africa's most populous country and the continent's largest economy.
As well as jihadists and criminal gangs known locally as bandits, Nigeria's security forces are also dealing with separatist agitation in the southeast.
