Hassan Rouhani: I'm proud Iranians trusted me to serve

President-elect of Iran Hassan Rouhani has called on the Iranian people to help him develop the country and preserve its national pride and interests.

In his first television appearance since his unexpected victory, Mr Rouhani thanked his supporters.

A senior American official, Denis McDonough, said the result was "a potentially hopeful sign" that progress can be made over Tehran's nuclear programme.

But despite a cautious welcome by western nations, Israel has warned against "wishful thinking".

Mr Rouhani has described the election result as a triumph of wisdom over extremism.
