In Nigeria, Ondo state Governor Rotimi Akeredolu has declared a week of mourning during which flags will fly at half-mast following Sunday’s attack at St Francis Catholic church.
Officials have not given a death toll, but eyewitnesses have said at least 25 people were killed.
The Bishop of the Catholic Diocese of Ondo says the attacked church, which is one of the biggest parishes in Ondo state, can hold up to 1,200 people.
Bishop Jude Arogundade called on the government to beef up security and arrest those behind the attack.
Nigeria’s medical association is calling on locals to go to nearby hospitals, where people are receiving treatment, to donate blood.
