The assassination of retired Nicaraguan army major Roberto Samcam in San José has sparked alarm over the safety of political exiles in
Costa Rica.
Samcam, a prominent critic of President Daniel Ortega, was shot multiple times in his home on June 19.
Human rights groups and exiled Nicaraguans allege the attack was orchestrated by Nicaraguan intelligence operatives.
Costa Rica's government faces criticism for its perceived inaction, as prior threats against Samcam had been reported.
The incident has intensified scrutiny of
Costa Rica's ability to protect refugees fleeing political persecution.
