BRUSSELS - The European Union may approve fresh sanctions against Iran within weeks, after a UN agency said Tehran had worked to design nuclear bombs, EU diplomats said on Thursday.
Iran denies trying to build atom bombs and its Supreme Leader Ayatollah Ali Khamenei said any US or Israeli attack on its nuclear sites would be met with "iron fists".
The United States and Israel have refused to rule out any option to prevent Iran from acquiring a nuclear arsenal.
Diplomats in Brussels said preliminary discussions among EU capitals on new measures had begun and plans may be ready for EU foreign ministers in Brussels to approve on 1 December.
"Experts are discussing a number of options on the table but it is difficult to foresee the outcome of the debate," one EU diplomat said. Another said he expected a formal decision to be reached on 1 December.
