Yes - Israel used this rather famously on ex-Nazis that they "extralegally imported" from around the world, even though a) the accused was not an Israeli citizen, b) none of the victims were Israeli citizens at the time of the crime, c) the crimes did not occur on Israeli territory. In most other cases those would be major jurisdictional issues.
