DHAKA: Iran has turned all of its enriched uranium closest to the level needed to make nuclear arms into more harmless forms.

The UN nuclear agency says, reports the BBC.

The conversion of its stock of 20%-enriched uranium was part of a deal to curb Iran’s nuclear programme.

The US said last week it would unblock $2.8bn in frozen Iranian funds in return for Iran’s compliance.

A four-month extension to talks on Iran's nuclear ambitions was agreed on Friday between Iran and world powers.

The talks are aimed at persuading Iran to limit its nuclear programme in exchange for the lifting of sanctions.

The six world powers involved in the talks - the US, France, China, Russia, Germany and the UK - suspect Iran seeks atomic weapons, which Iran denies.

The country insists that it is enriching uranium for use in nuclear power stations and for medical purposes.
