Around 1,000 Iranian students called on the country's leaders today to pull out of what they termed a "humiliating" deal to allow tighter inspections of Iran's nuclear facilities.
The students, who gathered in a central Tehran square after attending a prayers sermon nearby, said the decision to sign the Additional Protocol of the nuclear Non-Proliferation Treaty (NPT) was an insult to Iran's independence.
"Joining the protocol is humiliating for us. Why are we signing it from a weak position?" said one of the speakers at the brief rally as the audience chanted "Withdrawal from the NPT is our demand" and "Death to America".
Under pressure to dispel international fears it may be building atomic bombs, Iran agreed on Tuesday to co-operate fully with UN inspectors and suspend uranium enrichment in a deal brokered by Britain, France and Germany.
In a first step, Iran handed over a report to the UN nuclear watchdog yesterday that it said contained full details of its past and present nuclear activities.
Some commentators in Iran have criticised the agreement as a capitulation to the West.
