At a news conference with international media on Wednesday, Bolivia's President Evo Morales said relations with Peru are at "high risk" after the neighboring nation gave refuge to two more former Bolivian officials accused in the 2003 army killings of dozens of protesters.
Morales said his government is considering its response to what he calls a "provocation and an open aggression" by his Peruvian counterpart, Alan Garcia.
Peru said Tuesday that former officials Mirtha Quevedo and Javier Torres Goitia had requested and received refugee status. Unlike asylum, refugee status does not denote political persecution.
Bolivia had demanded that Peru hand them over, along with a third who was given asylum in April.
