ISTANBUL — Efforts by Turkey this week to repair relations with the United States and Europe stumbled over deepening concerns about the length and breadth of its state of emergency, which has been used to round up tens of thousands.

Europe’s top human rights official called on Turkey on Friday to lift the emergency decree, in place since a failed coup in July 2016, in an important speech in the capital, Ankara, at the Constitutional Court.

Secretary of State Rex W. Tillerson, who had little to show after his meeting with Turkish President Recep Tayyip Erdogan on Thursday, expressed “serious concerns” at the continued detention of American citizens under the crackdown.

Progress fell into a category of one step forward and two back. German officials, for instance, hailed a decision by a Turkish court on Friday to release a Turkish-German journalist, Deniz Yucel, in a case that has been a major irritant in relations.
