(CNN) -- Iranian authorities have blocked the word "Bahman" -- the 11th month of the Persian calendar -- from Internet searches within the country, according to an opposition website.
The measure appears to be an effort by Iranian authorities to obstruct access to several websites that are promoting a rally on Monday -- the 25th day of Bahman -- proposed by Iranian opposition leaders in support of the uprising in Egypt, Saham News reported Saturday.
Two Tehran residents also confirmed the block via e-mail to CNN.
