Iran's state TV says hundreds of university students have formed a human chain at an underground uranium enrichment facility to support their country's disputed nuclear program on the eve of the resumption of talks with world powers.

The report said the students gathered Tuesday at the gate of Fordo enrichment facility. Such human chain demonstrations have been common in the last decade.

The level of uranium enrichment is a key aspect of ongoing negotiations in Geneva that will resume on Wednesday. Halting 20 percent enrichment — a level Iran has acknowledged and which is several steps away from weapons-grade material — is a central goal of the West.

The West suspects Iran's nuclear program has a military dimension. Iran says the program is for peaceful purposes.
