Climate protesters in kayaks disrupt operations at Australia port

Australian police say they have arrested dozens of people during climate protests that claim to have halted two cargo ships at one of the world's biggest coal export ports.

Several activists engaged in "unsafe practices" on the water at the Port of Newcastle during the protests, New South Wales state police said.

Climate activist group Rising Tide, which claimed responsibility for the latest protest, said hundreds of activists paddled kayaks into the harbour's shipping lane.
