Munich (dpa) - Almost two years after she was sentenced to life in prison for her role in a string of neo-Nazi attacks, right-wing terrorist Beate Zschaepe's guilty verdict for the murder of 10 people has been set out in writing by a German court.

Zschaepe was blamed for the killings and two bomb attacks as a member of the National Socialist Underground (NSU), in a tortuous trial spanning more than five years that culminated in her guilty verdict in July 2018.

Two other members of the terrorist cell, Uwe Mundlos and Uwe Boehnhardt, committed suicide on November 4, 2011, as evidence mounted against them, leaving Zschaepe to face justice.

In its long-awaited written judgement, seen by dpa, the Higher Regional Court in Munich said that Zschaepe's contribution to the attacks, carried out between 2000 and 2007, had been "objectively substantial."

The exact arguments behind her conviction are of huge interest, since the verdict is yet to be assessed by Germany's Federal Court of Justice.

The 2018 ruling was based purely on circumstantial evidence.

What is known, however, is that Zschaepe lived for almost 14 years with Mundlos and Boehnhardt, during which time the two men murdered nine small business owners of Turkish and Greek descent and a police officer.

After their suicide, Zschaepe set fire to the trio's last residence, issued a taped confession and handed herself over to police.

She was later found guilty as an accomplice in all 10 murders and the bombings.

The written judgement says Zschaepe planned the attacks together with her co-conspirators and was tasked with "creating a safe retreat for the men" while they committed the crimes. Meanwhile, she stayed home or near home in order to be able to send the prepared confession video and destroy any evidence in case her friends were killed.

It wasn't until the video was released that authorities established the racist motive behind the spree.
