The tension between US and North Korea is rising. Now, it also affects the whole Korean peninsula.
A nuclear-powered submarine has arrived in South Korea to join an incoming group of warships.
According to a report, it has 154 Tomahawk cruise missile and 60 special operations troops and mini-subs.
The warship didn’t go directly to the Korean Peninsula, but is now proceeding to the region.
North Korea celebrated its army’s 85th founding anniversary with similar occasions, with missile tests.
On the other hand, North Korea released a threat, launching a “Super-mighty pre-emptive strike” against the US.
