Fox News reported on Monday that U.S. intelligence satellites have recently detected a North Korean patrol boat carrying antiship cruise missiles in the East Sea.

The U.S. broadcaster said the two Stormpetrel antiship cruise missiles were loaded on a patrol boat at Toejo Dong on the country’s east coast.  

U.S. officials told Fox News that it is the first time since 2014 that antiship cruise missiles were detected on a North Korean patrol boat.
