Accused by rivals of failing to ensure ceasefire in Sri Lanka, Tamil Nadu Chief Minister M Karunanidhi today went on a sudden fast declaring he was ready to be "yet another victim" of violence in the island nation.

In a surprise move, the 84-year-old chief minister drove to the memorial of late C N Annadurai early this morning and sat on a fast there demanding immediate ceasefire in the Sri Lankan army's offensive against the LTTE.
