Iran angry as sweeping UN sanctions take effect after failure of nuclear talks

Foreign ministry attacks unjustifiable' return of measures expected to have wide effects on troubled economy

Widespread UN sanctions against Iran have come back into force for the first time in a decade, prompting anger from Tehran, after last-ditch nuclear talks with western powers failed to produce a breakthrough.

The sanctions, which came into effect late on Saturday and three months after Israel and the US bombed Iran, bar dealings related to Tehran's nuclear and ballistic missiles programme and are also expected to have wider effects on its troubled economy.
