The US supercarrier Carl Vinson will arrive in the Sea of Japan in days, Vice President Mike Pence said Saturday in Australia, amid high tensions with North Korea.

"Our expectation is that they will be in the Sea of Japan in position in a matter of days, before the end of this month," he told reporters in Sydney.

The Trump administration has been trying to clear the waters after sending out confusing messages concerning the whereabouts of the Vinson carrier group that supposedly was steaming toward North Korea last week.
