The parade with a statue of the Virgin Mary was moving through the town of Ouahigouya on Monday when "a group of terrorists intercepted the procession, killing four worshippers and burning the statue," said a spokesman for the Ouagadougou Cathedral.
The killings came a day after a group of 20-30 armed men, according to witnesses, burst into the Catholic church in Dablo, also in the Nord Region of Burkina Faso, shooting dead five parishioners and their priest.
The attackers set fire to the church, several shops and a small cafe before heading to the health centre, which they looted, burning the chief nurse's vehicle.
Two days earlier, French special forces had freed four foreign hostages in Burkina Faso during an overnight raid that cost the lives of two soldiers.
Two weeks ago, there was a similar attack against a Protestant church in Silgadji, also in the north, when gunmen on motorbikes killed a pastor and five worshippers.
Burkina has suffered from increasingly frequent and deadly attacks attributed to a number of jihadist groups, including the Ansarul Islam group, the Group to Support Islam and Muslims (GSIM) and Islamic State in the Greater Sahara.
The raids began in 2015 in the north before targeting the capital Ouagadougou and other regions, notably in the east. Nearly 400 people have been killed since 2015 -- mainly in hit-and-run raids -- according to an AFP tally.
Jihadist groups target Christian clerics as well as Muslim ones they do not consider sufficiently radical.
Last month, jihadists attacked a village school in Maitaougou, in the eastern province of Koulpelogo, killing five teachers and a municipal worker.
