UNITE union has welcomed the release of Syrian Kurdish leader Salih Muslim, saying it was “disgusted” with Saturday’s arrest in Prague.

Mr Muslim was visiting the Czech Republic in an official capacity as the foreign affairs spokesman for the Movement for a Democratic Society, the broad political coalition that governs Rojava, the Kurdish region of northern Syria.

Turkey’s government, which is bent on repressing the country’s large Kurdish minority, was seeking Mr Muslim’s extradition from Prague, linking him to the outlawed Kurdistan Workers Party (PKK) which it regards as terrorists.
