Suspect held in New York jail has been linked to handler behind Iran-linked operations in Britain

When the US took custody of Mohammad Baqer Saad Dawood al-Saadi in May, investigators hoped the string of terrorist and arson attacks he was accused of promoting and directing against American and Jewish targets in the UK and Europe on behalf of Iran would stop. They were wrong.

An updated indictment, released on Tuesday by the US Department of Justice, describes some of what happened next. It reveals that al-Saadi has two allies, believed to be in Iran, also trying to provoke fear and chaos in the UK, one of whom is accused of orchestrating the September incident at RAF Fairford.
