Iranian President Hassan Rouhani has been met by hardline protesters as he arrived back in Tehran after attending the UN General Assembly's meeting in New York.
Hundreds of people gathered at Tehran Airport; some supporters hailed the trip, while several protesters chanted "Death to America".
During his trip, President Rouhani had signalled a shift in tone on Iran's controversial nuclear programme.
The visit culminated in a historic phone call with US President Barack Obama.
