The Kerala-Kudankulam march led by writers and social activists on Sunday to express solidarity with the anti-nuclear protests in Kudankulam was blocked by the police near the Kerala-Tamil Nadu border at Inchivila.

Kerala Anti-Nuclear Support Group, which organised the march, then tried to bus the activists to the protest site. But this attempt was also derailed when the bus was stopped and asked to return by TN police before Kudankulam.
