Environmental protesters in Australia brought the world's biggest coal terminal to a standstill on Sunday by blocking railway lines and chaining themselves to rail cars.
Police said they arrested about 37 people who chained themselves to a train and rail tracks at the port in Newcastle to protest over the impact of burning coal on climate change.
Three trains had to stop before getting to the terminal, meaning about 20,000 tonnes of coal could not be unloaded.
With consistent demand, much of it from China, 38.7 million tonnes of coal was shipped out of Newcastle in the first five months of 2008, according to port figures.
