A high court in Izmir said on Friday Brunson would stay under house arrest, upholding a decision taken by a lower court earlier this week. Brunson's lawyer said he would appeal again in 15 days.  The clergyman has been held since 2016 when he was arrested in a Turkish government crackdown following a failed coup bid. He faces 35 years in prison on espionage and terror-related charges. The court ruling comes amid a diplomatic spat between Turkey and the US that has seen tariffs from both sides pile up and an exchange of threats of further sanctions.
