Teheran hints at nuclear developments

Iran yesterday ruled out halting or limiting sensitive nuclear work in exchange for trade and other incentives from major powers and instead suggested it may announce new developments in the program this week.

Iran marks its National Day of Nuclear Technology today, an occasion President Mahmoud Ahmadinejad used last year to proclaim industrial uranium enrichment capacity.

Enriched uranium can be used as fuel in nuclear power plants or, if refined much further, provide material for weapons.
