Reports from Shiraz indicate that the campaign headquarters of reformist candidates Mohammdreza Aref and Hassan Rohani in that city were attacked.
The Jaras and Neday-e Sabz-e Azadi websites report that a group of plainclothes forces attacked the headquarters of the two candidates on Monday June 10.
The report adds that the heads of the youth branch of the two campaigns have also been summoned by security forces for questioning.
The attacks come a day after rumours were published about the possibility that the Guardian Council will reconsider the eligibility of Hassan Rohani to run in the election.
Today the Guardian Council denied the report, saying the Council is not looking to disqualify any of the approved candidates.
Eight candidates were approved to run in the election, and so far one conservative candidate, Gholamali Haddad Adel, has withdrawn in favour of his conservative peers.
The election will be held on Friday June 14.
