Chilean President Michelle Bachelet has condemned a bomb attack on a shopping centre in a busy metro station in the capital Santiago on Monday.
The attack, in which 14 people were injured, is one of the worst since democracy was restored in 1990.
Ms Bachelet called it a "terrorist act, one of the most cowardly we have seen".
There have been around 200 bomb attacks in Santiago in the past decade, with anarchist groups claiming responsibility for many of them.
No-one has so far admitted carrying out this latest bombing.
