Moscow and Beijing call for calm
The heightened tensions have prompted North Korea's traditional allies, China and Russia, to urge the different sides to keep a lid on the situation.
"Moscow expects all parties to exercise as much responsibility and restraint as possible in light of North Korea's latest statements," the Russian foreign ministry said Saturday according to Russian state broadcaster Russia Today.
China, which expressed frustration over Pyongyang's most recent nuclear test, also called for calm.
"We hope relevant parties can work together to turn around the tense situation in the region," Foreign Ministry spokesman Hong Lei said Friday, describing peace and stability on the Korean Peninsula as "a joint responsibility."
But the coming weeks appear laced with potential for more bouts of saber-rattling.
North Korean delegates are currently gathered in Pyongyang for the Supreme People's Assembly, the country's rubber stamp parliament.
And April 15 is the anniversary of the birth of Kim Il Sung, the nation's founder and the grandfather of Kim Jong Un. That day, the biggest national holiday in North Korea, is usually marked by large-scale parades.
Meanwhile, the U.S.-South Korean military exercises that have already stirred so much ire from the North are due to continue until the end of the month.
Some analysts have noted that Pyongyang has carried out some sort of military provocation within weeks of every South Korean presidential inauguration.
Park, the current president, took office on February 25, five weeks ago.
"You can't put it past them the idea that they are ... trying to establish a new equilibrium in which they are accepted as a nuclear weapons state," Victor Cha, former director of Asian affairs for the U.S. National Security Council and now a Georgetown University professor, said about North Korea.
