The first full day of US-Iran talks in Switzerland ended with Washington and Tehran offering differing accounts of what had been agreed, particularly on the issue of international inspections of Iran’s nuclear programme.

The US seeks Iran's agreement to nuclear site inspections in exchange for releasing $6 billion in frozen funds during the first round of peace talks in Switzerland.

At issue is whether Iran will be allowed to continue enriching uranium and what it will do with the uranium it possesses.

Iranian state media says nuclear inspectors weren’t discussed in Switzerland.
