KOLKATA, India, Oct 13, 2007 (AFP) - Six activists of the environment group Greenpeace were arrested for scaling the chimney of a thermal power plant in eastern India to highlight damage caused by pollution, police said on Saturday.

The activists scaled a 250-feet (76 metres) high smokestack of the Kolaghat plant, 90 kilometres (50 miles) west of Kolkata, capital of West Bengal state.

They were seeking to spotlight the threat to the environment from coal-fired power plants, Greenpeace spokeswoman Joyshree Nandy said.

SYDNEY, Sept 3, 2007 (AFP) - Environmental activists targeting an Asia-Pacific summit meeting broke into an Australian power station Monday and chained themselves to a conveyor belt, a company spokesman said.

The Loy Yang power station in the south-eastern state of Victoria activated emergency procedures and reduced power output after four demonstrators locked themselves onto the coal-carrying belt, the spokesman said.

Loy Yang Power owns and operates a 2,000 megawatt station and an adjoining coal mine and supplies about 30 percent of Victoria's electricity demand.
