Tehran, June 6, IRNA � A nuclear deal with Iran will reduce Tehran�s enrichment capacity, US Vice President Joe Biden�s national security adviser told a conference in Qatar on Monday, AFP reported.

Colin H. Kahl, speaking at the US-Islamic World Forum in Doha, said the current deal being hammered out was the best on offer, despite skeptical voices in the US and elsewhere, including Persian Gulf Arab states.

�Under the deal we are negotiating... Iran�s enrichment capability will be substantially rolled back,� said Kahl.

�The deal we are negotiating makes us and the region safer.�

The negotiators engaged in the ongoing talks between Iran and the major powers on a nuclear accord are trying to bridge differences, especially over a monitoring and verification regime regarding Tehran�s nuclear program.

Other sticking points remain, including the UN nuclear agency�s investigation into what it calls possible military dimensions of Iran�s nuclear work and the demands by some major powers for UN inspections of Iranian military sites, which have been rejected by Iran.
