VIENNA (AFP)---An Austrian court said Friday that alleged Croatian Nazi war criminal Milivoj Asner has been declared senile for a fourth time, preventing his extradition to his homeland for trial.

The expertise came despite Asner, 95, giving media interviews after being spotted celebrating among Croatian football fans in the southern Austrian town of Klagendurt where he lives.

" The new report states that Asner is not fit to be heard in court" due to his fragile mental health, Klagenfurt prosecution spokesman Helmut Jamnik told AFP.

The latest psychiatric examination was ordered by the court following angry reactions to pictures published in British tabloid The Sun on Monday showing Asner and his wife relaxing on the terrace of a cafe and walking with Euro 2008 football fans in the town.

" On the basis of the new report, the judge will decide on further steps in the case," Manfred Herrnhofer, spokesman of the Klagenfurt provincial court in charge of the case, added.

" The photos are one thing, the experts' opinions are another and they are to be taken seriously," he added.

Three previous medical reports -- the latest of which dates from last April -- have found that Asner was not fit to stand trial.

The Nazi-hunting Simon Wiesenthal center and other international organizations questioned the validity of these reports and accused Austria of trying to protect Nazi war criminals.

Apparently in good shape, Asner declared in several interviews given among others to the Croatian public television this week that he was "ready to come to Croatia" to face justice.

Born in 1913 and living in Klagenfurt for two years, Asner is wanted by Zagreb for crimes committed during World War II, when he served as a police chief under Croatia's Nazi-allied Ustasha regime.

He is accused of having organised the deportation of Serbs, Jews and gypsies to concentration camps, where most of them were killed.

Asner told Croatian national television Thursday cost considerations meant they were expelled from Croatia.
