According to the official IRNA news agency, hard-line student leader Esmaeil Ahmadi said the students want to fight Israel in support of Hamas – Gaza's Islamic militant rulers.
Five hard-line student groups and a conservative clerical group launched a registration drive last week to ask the government to allow them to stage the suicide attacks.
President Mahmoud Ahmadinejad's government has not responded to the call yet.
The government never responded to similar requests in the past. This raises the likelihood that the calls are mainly for propaganda purposes.
