Eli Lake reports: The regime in Tehran has been more brutal to its opponents in recent months. A video surfaced over the weekend of the leader of Iran's striking bus drivers, Mansour Osanloo, discussing and showing the results of his torture, including a gash on his chin and a hole in his tongue, at the hands of his jailors earlier this year. The torture of Mr. Osanloo was first reported by The New York Sun in March.
