Investigation launched after German prison paid £6,000 to convicted 9/11 accomplice

Germany is facing international embarrassment after it emerged that prison officials paid a convicted 9/11 accomplice €7,000 (£6,000) in cash.

Mounir al-Motassadeq is one of few people ever convicted over 9/11. He was deported from Germany last year after serving a 15-year sentence as an accessory to the 2001 attacks, in which almost 3,000 people were killed.

It has now emerged that before being flown to his native Morocco, the 44-year-old was handed €7,000 in cash as payment for prison work.
