Just one day after six Catholics were murdered by gunmen in Burkina Faso, four more Catholics were shot and killed in the northwest African country.

On Monday, unknown gunmen interrupted a religious procession in a village near Kongoussi, a northwest city of the Bam Province. After releasing the children, the assailants killed four adult worshipers and burned a Marian statue, according to reports.

“We will not be bogged down by the religious attacks,” said Cardinal Philippe Ouédraogo, archbishop of Ougadougou, CNN reported.
