Guna: Congress General Secretary Digvijay Singh on Friday expressed sympathy for the beleaguered former Samajwadi Party leader Amar Singh who was arrested in the cash-for-vote scam case two days ago.

"I have full sympathy for Amar Singh and I believe that he will be proved innocent," Singh told reporters at Raghogarh near here.

He also strongly condemned Thursday's blast outside the Delhi High Court and asked people not to politicise the issue of terrorism.

Terror activities should be curbed with an iron hand and fundamentalists of any community should not be spared, he said.

When asked about Anna Hazare, he said he respects the Gandhian a lot, and would like to congratulate the social activist for two things: he forced the RSS people to  wear white caps instead of (the usual) black ones, and hold the national tricolour in hand, in place of RSS's saffron flag.

Singh denied that he had ever described Hazare as the mask of the RSS.
