North Korea claims it is entering a "state of war" with South Korea, according to its state run news service.
This announcement comes a day after North Korean leader Kim Jong-un issued an order to put missile units on standby to attack U.S. military bases in the South.
The White House said Saturday it takes North Korea's latest threats seriously while cautioning that Pyongyang has a long history of amped-up rhetoric, Reuters reports.
"We take these threats seriously and remain in close contact with our South Korean allies," said Caitlin Hayden, spokeswoman for the White House National Security Counci. "But, we would also note that North Korea has a long history of bellicose rhetoric and threats and today's announcement follows that familiar pattern."
North Korea's recen threats comes after America recently flew two nuclear-capable stealth bombers over the Korean peninsula in a military exercise to reassure U.S. allies in the region.
Hayden said the U.S. is prepared to stand by its allies, Reuters reports.
"We remain fully prepared and capable of defending and protecting the United States and our allies," said Hayden.
