Israeli Prime Minister Benjamin Netanyahu has accused the West of dragging its heels over Iran’s disputed nuclear programme.
He also said the enrichment of uranium has to stop, if he is to believe a nuclear weapon is not the goal.
Netanyahu’s comments come after world powers recently held talks with Iran in Baghdad.
According to one Israeli official, the discussions achieved nothing.
Iran denies that it is setting its sights on a nuclear weapon.
World powers have scheduled a further round of talks, in Moscow, in June.
