Lawyer says 81-year-old American held in Iran has surgery

A lawyer says an 81-year-old Iranian- American imprisoned in Iran on widely criticised spying charges has undergone surgery and had a pacemaker installed.
Washington-based attorney Jared Genser said in a statement that Baquer Namazi is expected to return to Tehran's Evin prison today.
Genser says Namazi underwent surgery yesterday. He says his client has been in poor health.
Namazi is a former UNICEF representative who served as governor of Iran's oil-rich Khuzestan province under the US- backed shah.
Both he and his son, Siamak, are serving 10-year prison sentences after being convicted of "collaboration with a hostile government," namely the United States.

A United Nations panel this week described their "arbitrary" detention as part of an "emerging pattern" by Tehran of targeting dual nationals.
