Someone's feelings are hurt. Somebody needs a hug.
"The supreme command of the Korean People's Army Tuesday issued an ultimatum to the South Korean puppet group," Pyongyang's official news agency, KCNA, said.
Threatening that it would not give any advance notice before attacking South Korea, the North warned: "Our retaliatory action will start without any notice from now."
North Korea said it was responding to insults from the "puppet authorities" in the South, who yesterday held a rally against the North in Seoul.

Branding the rally a "monstrous criminal act," the North warned "all the service personnel and people of the DPRK are simmering with towering resentment" towards the South.
"Our retaliatory action will start without any notice from now as such thrice-cursed criminal act of hurting the dignity of the supreme leadership of the DPRK is being openly committed in the heart of Seoul under the patronage of the puppet authorities."
"The DPRK's revolutionary armed forces will start immediately their just military actions to show how the service personnel and people of the DPRK value and protect the dignity of the supreme leadership."
"The military demonstration of the DPRK's revolutionary armed forces will be powerful sledge-hammer blows at all hostile forces hurting the dignity of the supreme leadership of the DPRK."

The renewed threats came a day after U.S. Secretary of State John Kerry urged the regime in Pyongyang to halt its nuclear program and tame its fiery rhetoric if it wants to hold talks.
However, today the North responded by saying "if the puppet authorities truly want dialogue and negotiations, they should apologize for all anti-DPRK hostile acts, big and small, and show the compatriots their will to stop all these acts in practice."
The Secretary of State's visit followed weeks of dramatic threats by Kim Jong Un's regime, including that of a nuclear strike on the United States and South Korea.
