US authorities have dropped charges against two researchers accused of attempting to export chemicals to Iran in violation of trade sanctions. The decision follows a prisoner swap in which the United States freed a third researcher who was charged alongside them — and imprisoned. Iran released a jailed US researcher in exchange and both were allowed to return to their home countries last week.
