0955 GMT: Latest from Tehran. Hundreds of security forces are on patrol near the universities.

0720 GMT: The Battle Within. A vivid reminder of the contest developing within the system....

Speaker of Parliament Ali Larijani on Monday criticised certain principlist groups which take an "aggressive” position: "Principlists should follow a strategy of tolerance toward each other.”

Larijani continued, "There are disagreements among the principlists and this fact can not be overlooked. (But) the principlists should notice that the true principlists who formed the principlist front are still loyal.”

Even more striking was Larijani's implication of a challenge against some of those causing divisions: "There are some figures among the principlists who cause some concerns. They should be guided."

Larijani did not give specific names, but it is safe to say that his comments were generally directed at the President's loyalists (and maybe the President).

Statements from Universities calling for today's protests are scattered throughout our updates of the last two days. Josh Shahryar offers a selection of them this morning.
