Eight Greenpeace activists were arrested Thursday morning as they entered an coal-fueled electrical power plant in Hadera in an attempt to disrupt coal breakdown operations.

The activists entered the power plant through the sea with inflatable dinghies and climbed up ropes to reach an elevated seaside coal dock.

Greenpeace spokeswoman Hila Krupsky says activists climbed on to a massive crane and unfurled a huge, Hebrew banner reading “coal kills.” She says the protest held up coal deliveries.

The electrical company’s security guards called local police and eight activists were detained, three Israeli nationals and five foreign citizens.

The power plant infiltration was in protest of the use of coal to fuel power plants and the planned building of another coal-fueled electrical plant in Ashkelon.

On July 9, Greenpeace activists from Israel and Germany climbed a coal ship making its way from South Africa to Israel, attempting to block it from docking in Hadera. Three of the activists climbed the side of the Orient Venus with a rope ladder waving a flag which read “coal kills.” The three were arrested by police and later released.

In 2009, 10 Greenpeace activists were arrested after they conducted a demonstration at the Ashkelon coal-fueled power plant and blocked the entrance to the facility.
