New Delhi, Sep 25 (ANI): Even as one of the men accused in Ajmer Dargah bomb blast in 2007, has accused several union ministers and senior Congress leaders, besides National Investigation Agency officers of pressuring him to implicate RSS chief Mohan Bhagwat and senior RSS functionary Indresh Kumar in the attack, senior Congress leader Rashid Alvi said that it's a baseless letter and it is clear that BJP or RSS leaders are behind it.
