Bodu Bala Sena, or BBS, is widely believed to have the backing of the current government and has endorsed Rajapaksa’s re-election. Over the past two years BBS has been involved in many attacks on religious minorities and dissenting civil society groups. While the group has been relatively quiet the past few months, many believe it may return to action either before or after the election, perhaps to intimidate or complicate campaigning by the opposition, or to reduce turnout in Muslim-majority areas. http://blog.crisisgroup.org/asia/2014/12/11/sri-lankan-election-the-tighter-the-race-the-more-violent-it-threatens-to-be/
