ETA in Portugal?

Investions have begun to establish whether ETA has created a temporary base in Portugal. Spanish investigation teams will work with their Portuguese counterparts in the same way they already do with the French. Spanish anti-terrorist experts believe there is an ETA base in the south of the country operating out of an isolated, rented house. Portuguese police doubt that this base exists although they acknowledge that there is ETA movement in their country.
