At Shahid Beheshti University, they carried pictures of Iranian nuclear scientists assassinated over the past decade.

A similar rally was held at Tehran's Sharif University of Technology, where students formed a symbolic human chain, Press TV said.

They called on state officials to prevent such visits which have sparked a flurry of condemnation by some Iranian officials.

Last week, former head of the Atomic Energy Organization of Iran (AEOI) denounced as "unacceptable" the recent inspections of two Iranian universities by International Atomic Energy Agency (IAEA) inspectors.

Fereidoun Abbasi, warned against what he called free access to the country's sensitive sites.

The IAEA inspections of Iranian academic centers were an inherently "wrong and unacceptable" move, Abbasi said.

The IAEA is monitoring Iran's nuclear plan under the Joint Comprehensive Plan of Action (JCPOA). Under the plan, Iran agreed to implement the Additional Protocol to the Non-Proliferation Treaty.
