The United States sharply criticized Germany on Thursday for deporting a convicted terrorist to Turkey despite an extradition request for him to stand trial in a New York court.

Adem Yilmaz was deported on Tuesday to his native Turkey after serving an 11-year prison sentence in Germany for planning a 2007 bomb plot to attack American citizens and facilities in Germany as part of an Islamist extremist cell.

The United States had requested his extradition to face terrorism charges for conspiring to carry out a 2008 suicide bombing near the Afghanistan-Pakistan border that killed two US soldiers and injured 11 other people. Yilmaz, a member of a group called the Islamic Jihad Union, is also accused of carrying out attacks on US troops on the Pakistan-Afghanistan border in 2006.

New York prosecutors filed the indictment against Yilmaz in 2015, but it was only unsealed at around the time he was being deported from Germany to Turkey.
