No mention here of who made the list or who is on it, but since it is coupled with the threats to Austria and Germany, it seems clearly jihad related. "List of politicians as possible attack targets surfaces in Austria," from AP (thanks to Joel):
Austrian authorities have found a list of politicians circulated online as potential targets for attacks, an Interior Ministry spokesman said Friday. But, while they notified the people on the list, they said there were no indications any of them were ever in danger.
Authorities found the list during an investigation of a video posted online in March threatening Austria and Germany with attacks if they did not withdraw military personnel from Afghanistan, said Rudolf Gollia, the Interior Ministry spokesman.
