Germany's top court has rejected the appeal of a suspected Islamic State member from Tunisia against deportation to his homeland.

The Federal Constitutional Court noted Monday that German authorities had obtained assurances that the man, in his late 30s and identified only by the initial S., wouldn't face capital punishment.

S. was arrested in Frankfurt last year on suspicion of being a recruiter and smuggler for IS since August 2015, and of planning an attack. Tunisia accused him of involvement in the March 2015 attack on the Bardo museum in Tunis, as well as a March 2016 attack on the border town of Ben Guerdane.

His lawyer, Seda Basay-Yildiz, told The Associated Press she has submitted an urgent appeal to the European Court of Human Rights to halt his deportation.
