UN nuclear head arrives in Iran for talks: state media

International Atomic Energy Agency chief Rafael Grossi arrived in Iran's capital Tehran on Wednesday for critical talks on the country's nuclear programme, state media reported.

The visit comes against the backdrop of tit-for-tat attacks by Iran and its sworn enemy Israel and a week after Donald Trump -- a noted hawk on Iran -- won the US presidential election.

State television broadcast images of Grossi's arrival at the airport terminal in Tehran.
