"Sharply increased movements of vehicles and soldiers have been detected recently at North Korea's mid and long-range missile sites," South Korea's Yonhap news quoted a military source as saying.

"There is a combat duty readiness in effect at the North's missile units since February 26 so there is a possibility they will actually fire."

Army and People of DPRK Pledge Revenge on Enemies: CPRK Secretariat

Pyongyang, March 29 (KCNA) -- The Secretariat of the Committee for the Peaceful Reunification of Korea (CPRK) released its information bulletin No. 1027 Friday which says as follows:

The service personnel and people of the DPRK have turned out as one in the sacred war for annihilating the enemy, their hearts burning with towering hatred and resentment at the U.S. imperialists and south Korean group of traitors going reckless in their moves to destroy the symbol of the supreme dignity of the DPRK, not content with staging war exercises against the north.

Upon hearing the statement of the Supreme Command of the Korean People's Army, all service personnel and people are renewing their firm resolution to deal merciless and retaliatory blows at the vicious provocateurs and achieve a final victory in the war for national reunification.

Terrified by the toughest measures taken by the DPRK recently, the south Korean puppet group is letting loose a spate of invectives that those measures are aimed to "rally forces to consolidate the social system" and an "intentionally orchestrated farce" and spreading all kinds of lies against the dignity of the supreme leadership of the DPRK.

These are scream and desperate efforts of those frightened by the invincible might of the DPRK winning victory after victory with all the service personnel and people united close around the brilliant commander of Mt. Paektu in single mind and their high spirit to annihilate the enemies.

The puppet group seems to have lost the ability of discerning the situation being stupefied with amazement.

One month has passed since the new regime emerged in south Korea but the support ratings have been in the doldrums being forsaken by the people's mindset. The regime has not yet formed the "government" owing to all scandals. So, the ruffians of the puppet regime dare cry out for "insecurity of social system" of the DPRK though the regime is just like a house in mourning. This can not but be a laughing stock.

No sooner had the new puppet regime emerged than it shelved its dirty plight on the eve of a collapse and let loose a spate of invectives against the DPRK in a bid to tarnish the high international authority and image of the DPRK and evade its retaliatory blows. This is arousing derision of people as it acts like a mad dog barking at the sky.

The puppet group is sadly mistaken if it thinks it can hurt even a bit the unbreakable single-minded unity and the image of the dignified DPRK in which all service personnel and people have formed a harmonious whole with their leader.

The group should know that the statement of the Supreme Command of the Korean People's Army and the declarations of the great Paektusan nation are the eruption of the strong faith and will of its army and people to devotedly defend the leader.

Anyone who goes reckless, hurting the dignity of the supreme leadership and the social system of the DPRK, will never be pardoned but they will be destroyed as the first target as had already been declared.

The DPRK's army and people are compelled to take notice of the ever stepped-up anti-DPRK invectives by the puppet group instigated by the venomous swish of skirt of the owner of the inner room of Chongwadae.

The group of traitors pointing their fingers at the sky will never be able to evade punishment.

Kim Jong Un Operation Convenes Meeting, Finally Ratifies Examines and Plan for Firepower Strike

Pyongyang, March 29 (KCNA) - The moves of the U.S. imperialists to violate the Sovereignty of the DPRK and supreme encroach upon its Interests have Entered a serious phase.

Not content with letting B-52 sorties over South Korea make in succession DESPITE the Repeated warnings, They Made B-2A stealth bomber and other strategic strategic strike means fly from Whiteman Air Force Base in Missouri State, the U.S. over South Korea on March 28 for the first time in history to commit dangerous provocation Such as staging a drill Openly for striking ground targets of the DPRK.

Proves That This fully brigandish the ambition of the U.S. imperialists for aggression to stand in confrontation With The DPRK has Reached an extreme phase meaningful defying the warning made ​​by its revolutionary armed forces in the March 26 statement of the Supreme Command of the Korean People's Army.

In view of the prevailing grim situation, Supreme Commander of the Korean People's Army Marshal Kim Jong Un , first secretary of the Workers' Party of Korea and first chairman of the National Defence Commission of the DPRK, convened meeting an urgent operation on the KPA Strategic Rocket Force's performance of duty for firepower strike at the Supreme Command at 00:30 Friday.

Present Yong Hyon Chol There Were, chief of the KPA General Staff, Ri Yong Gil, director of the Operation Bureau, Kim Yong Chol, director of the Reconnaissance General Bureau, and Kim Rak Gyom, commander of the Strategic Rocket Force.

At the first meeting I received a report from General Kim Yong Chol, vice chief who también of the General Staff of the KPA, on the information about the nature of nuclear strike action of the means of the U.S. imperialist aggressor forces.

After Receiving a report from Lieut. General Kim Rak Gyom on the technical conditions of the strategic strike means of the KPA, I made ​​an important decision.

I've said I've Judged the time has come to settle accounts With The U.S. imperialists in view of the prevailing situation.

If They make a reckless provocation with huge strategic forces, the KPA Should mercilessly strike the U.S. mainland, Their stronghold, Their military bases in the operational theaters in the Pacific, Including Hawaii and Guam, and Those in South Korea, I said. Examined and finally I Ratified the plan of the Strategic Rocket Force for firepower strike.

The U.S. imperialists let B-2A make sorties over South Korea in succession, indicating once again Their hostile acts against That the DPRK have Entered a reckless phase, going beyond the phase of threat and blackmail, I said.

B-2A's flight to the sky above South Korea is not a simple demonstration of forces in reaction to the tough stand of the DPRK but an ultimatum That They Will ignite a nuclear war at any cost on the Korean Peninsula, I NOTED, underlining the need to put a definite end to the times When They Could Threaten and blackmail the DPRK with nukes.

I've Declared the revolutionary armed forces of the DPRK would react to the U.S. nuclear blackmail with a nuclear merciless attack, and war of aggression With An all-out war of justice.

I've finally signed the plan on technical preparations of strategic rockets of the KPA, ordering them to be standby for fire so That They may strike any time the U.S. mainland, its military bases in the operational theaters in the Pacific, Including Hawaii and Guam, and Those in South Korea.

He said the enemies are bringing dark clouds of a nuclear war testing the DPRK's self-restraint, adding the DPRK can no longer tolerate this. I ordered the KPA to blow up and reduces everything to ashes at a single strike, if an order is issued.

I've said the heroic service personnel of the KPA and all other people, Their hearts burning with irrepressible resentment at the reckless war provocation moves of the U.S. imperialists, are now waiting for a Final Order of the WPK Central Committee, hardening Their will to turn out in a do-or-die Battle with the enemies.

REMAIN The KPA will never passive onlooker to the U.S. imperialists to 'frantic moves for aggression but do its best to defend the destiny of the country and nation, I said.

It is the truth confirmed by history That no force on earth can hold in check the people all out for the just cause, I NOTED, stressing if an undesired war breaks out again on This Land due to the Consequences of the unpardonable action of the U.S. imperialists, it will bring them to ruin and the Korean shameful nation will greet the bright day of national reunification.

The important decision made ​​by him under the severe situation where the Korean Peninsula has been pushed to the brink of a nuclear war by the U.S. imperialists will mark a turning point in putting an end to the history of the long-standing showdown With The U.S. and opening a new phase of history.

Thousands of North Koreans have turned out for a mass rally at the main square in Pyongyang in support of their leader's call to arms. - AP
