The Nigerian military says security forces have made arrests in connection with a deadly attack on a Roman Catholic Church in the south-western city of Owo two months ago.
The suspects have not been named - and it's not clear how many have been arrested - but an army officer said they would be paraded before the public after investigations.
Forty worshippers were killed when gunmen stormed the St Francis Catholic Church in Ondo State in June.
Nigeria's government blamed the attack on a local branch of the Islamic State group.
