European Union foreign policy chief Javier Solana was due in Tehran late yesterday to deliver a package of incentives that seek to persuade Iran to abandon its plans to make nuclear fuel, Iranian sources said.

One of the sources, who all asked not to be identified, said Solana would meet Iranian officials today. An EU diplomat also claimed that Solana would be in Iran today but gave no further details either.

Speaking during a visit to the West Bank city of Ramallah, Solana said he would travel to Iran ?very soon?, but did not elaborate.

He arrived in Israel late on Sunday as part of a previously planned trip that includes meetings with Israeli and Palestinian leaders. His spokeswoman said he was to have dinner with Palestinian civil society leaders in Ramallah last night.

The incentives Solana will deliver to Iran stem from an initiative put together by the three biggest EU states ? Britain, France and Germany ? and were approved by a forum that also included the United States, China and Russia. Solana?s office in Brussels said it was preparing an announcement about the details of the trip but for now could not be more precise about the timing. Details of the package have not been announced, but diplomats have been working on themes ranging from offering nuclear reactor technology to giving security guarantees.

President Mahmoud Ahmadinejad said on Saturday Iran would consider incentives but insisted the crux of the package ? that Iran must give up uranium enrichment ? was still unacceptable.

Western nations fear Iran is enriching uranium to make an atomic bomb, but Iran insists its aims are entirely peaceful and that it wants to make fuel only to generate electricity.
