Iran has agreed to hand over a US permanent resident imprisoned for years in Tehran to Lebanese officials, an Iranian judiciary official said Tuesday, providing the first official confirmation that Nizar Zakka would be sent back to his native Lebanon. The comment by judiciary spokesman Gholamhossein Esmaili comes as a top Lebanese security official is in Tehran to secure Zakka's release, which has been anticipated for days.
