DUBAI/LONDON (Reuters) - British Prime Minister Theresa May raised concerns on Tuesday with Iran's President Hassan Rouhani over several cases involving dual British-Iranian nationals, including imprisoned aid worker Nazanin Zaghari-Ratcliffe, her office said. Zaghari-Ratcliffe, 37, who was detained in early April as she tried to leave Iran after a visit with her two-year-old daughter, is accused by Iran's Revolutionary Guards of trying to overthrow the Iranian government.
