Six underground storage tanks at a nuclear site in the US state of Washington have been leaking radioactive waste, officials have said.

The seeping at the Hanford Nuclear Reservation poses no near-term danger of polluting the Columbia River and the leak provides no immediate health risk, state governor Jay Inslee said.

But he described the updated findings, which come a week after radioactive waste was found at one tank on the site, as "disturbing news for all Washingtonians".
