The bodies of two Spanish journalists, David Beriain and Roberto Fraile and an Irish wildlife activist Rory Young, arrived in Spain by military plane early Friday.
AFP reports that The Airbus 310 carrying the bodies landed at a military airbase in Torrejón de Ardoz, east of Madrid, at 9:00 am (0700 GMT).
The three were killed after an attack on the convoy in which they were travelling in Burkina Faso.
The two journalists were filming a documentary on poaching when they were ambushed and killed and now join the list of journalists who have died in conflict zones.
Rory Young was a Zambian-born, Irish conservationist. He was the president and co-founder of the anti-poaching organization Chengeta Wildlife that is active all over Africa.
In a joint statement, issued by the French foreign ministry, France, Germany, Spain and Italy, the countries on Friday condemned the killing of the three.
The four countries announced they would continue to work alongside regional and international partners to fight against terrorism in that part of Africa.
