LONDON, May 2 (AFP) May 02, 2008 -- US Secretary of State Condoleezza Rice said Thursday she was determined not to give ground over a package of "incentives" that the West has offered up to convince Iran to give up its nuclear programme. The top US diplomat, who arrived in London for talks on Friday on Iran, the Middle East peace process and Kosovo, insisted on the need to "fully" implement United Nations sanctions levied on Tehran. "We will take a look again at what we have offered the Iranians," she told journalists on the plane en route to Britain.
