negotiations on Iran's nuclear programme, amid rising expectation of a breakthrough.

US Secretary of State John Kerry is heading to Geneva to join negotiations on Iran's nuclear programme, amid rising expectation of a breakthrough.
Mr Kerry had been on a tour of the Middle East, but changed his plans at the invitation of the EU foreign policy chief Catherine Ashton.
Iran's foreign minister said a deal could be reached on Friday.
The Israeli prime minister said such an agreement would be "very bad" and Israel would not be bound by it.
The talks bring together world powers - the five permanent Security Council members plus Germany (P5+1) - and Iran.
