I doubt it, but it would certainly be nice to nail her and Sgrena, both of them terrorist sympathizers, inciters and funders. Sgrena is even responsible for the death of one of the Italian special forces who rescued her, since the Italian govt didn't want to reveal the fact that they had ransomed her and the driver tried to blow through a US checkpoint.
Of course, Italy is now trying to bring the US into the courts over this, so I think you can see how effective the EU is on this.
