International Atomic Energy Agency (IAEA) officials have renewed talks with Iranian envoys in a bid to persuade Tehran to allow IAEA experts to visit a suspect site at the Parchin military complex.
Iranian president Mahmoud Ahmadinejad yesterday asked the west to "correct its manners" if it wanted the respect of Iranians.
"If the West corrects its manners and respects the Iranian people, in return it will gain the respect of the Iranians," the official IRNA news agency quoted Ahmadinejad as saying in the northeastern city of Qoochan where he is on a provincial tour.
"They should know that the Iranian nation will not retreat a step over its fundamental right," he said.
A senior UN nuclear agency official has urged Iran to allow access to sites, people and documents it has been seeking on suspicions that Tehran had conducted secret research into nuclear weapons development.
According to the agency, Iran used the Parchin military complex to test multipoint explosives of the kind used for setting off nuclear charge. Iran has denied such experiments and insists it had no plans to turn its civilian nuclear programme to making weapons.
