VIENNA, Oct 8, 2008 (AFP) - An Austrian Islamist woman, sentenced to jail for helping air an Internet video threatening attacks in Austria and Germany, was freed Wednesday pending retrial, the appeals court in Vienna said.

'Extending the pre-trial custody seems disproportionate, as no date has yet been set for the second trial in the Mona S. case and we are therefore unlikely to have a legal ruling in the foreseeable future,' said court spokesman Raimund Wurzer.

Mona S., 21, was sentenced to 22 months in jail in March for translating a video made by her husband, Mohamed M., a 22-year-old Austrian of Egyptian origin.

He was given a four-year mandatory prison sentence.

In the video, aired March 2007, the 'Global Islamist media front' had threatened Austria and Germany with attacks if the two countries did not withdraw their troops from Afghanistan, according to the prosecution.

The clip included threats against several targets during the European football championship -- which took place in Austria and Switzerland in June -- as well as threats against Austrian and foreign politicians.

However, a Vienna court announced in late August the couple would be retried as documents submitted to the supreme court as part of their case were incomplete.

The court rejected a first request to have Mona S. freed in mid-September after deeming her a potential repeat offender.
