Scaling up their protest against loading of fuel at the Kudankulam Nuclear Power Plant, anti-nuclear activists and fishermen on Saturday tried to lay siege to the port here but work was not disrupted, officials said.
About 3,000 fishermen and anti-nuclear activists in 500 mechanised and country boats tried to block the approach channel where ships enter the port but were prevented by Indian Coast Guard and CISF personnel, CISF and port authorities said.
The protesters remained in the sea shouting slogans against central and state governments asking them to stop loading of fuel at the plant, which began on Wednesday, they said.
Meanwhile, a group of anti-nuclear activists organised a human chain in Tuticorin town.
Peoples Movement Against Nuclear Energy, spearheading the over year-long stir, had given the call on September 20 to fishermen to stall port activities at Tuticorin, Kanyakumari, Rameswaram and Chennai on Saturday.
