Aboard The USS Curtis Wilbur: US and South Korean naval ships fired artillery and dropped anti-submarine bombs off South Korea's east coast Tuesday, the third day of high-profile military manoeuvres intended to warn nuclear-armed North Korea against further aggression.
The dramatic show of force comes four months after a South Korean warship sank in the waters off the Koreas' west coast, killing 46 sailors.
An international team of investigators determined that a North Korean submarine fired a torpedo that sank the ship in what Seoul called the worst military attack on it since the 1950-53 Korean War.
So far, there was no sign North Korea was preparing the military response it had threatened before the drills — which the communist labelled provocation — began on Sunday, military officials said.
The Korean peninsula technically remains in a state of war because the conflict ended in a truce, not a peace treaty. Yesterday, both Koreas and the United States marked the 57th anniversary of the signing of the armistice against the backdrop of the military drills.
Pursuit of liberty
"Since our nation's founding, the United States has relied on our armed forces to ensure our safety and security at home, and to protect lives and liberties around the globe," President Barack Obama said in a statement.
"I call upon all Americans to observe this day with appropriate ceremonies and activities that honour our distinguished Korean War veterans."
In the North's capital, Pyongyang, soldiers and citizens marked the anniversary by laying bouquets at the foot of the Korean War memorial, footage from TV news agency APTN showed.
North Korea, which denies any role in the sinking of the Cheonan, has strongly protested the exercises.
In flourishes of rhetoric typical of the regime, the regime has vowed a "nuclear" response in recent days.
"This is an impure attempt to stifle [North Korea] by means of armed force," North Korean army officer Hong Sung Chol told APTN in Pyongyang.
"If the US imperialists ignite war again, our army and people will totally uproot the source of the war under the leadership of our brilliant commander, General Kim Jong Il."
The regime has also pressed its demand for a full peace treaty.
"Military tension and the danger of war on the Korean peninsula would not be addressed for good unless the United States abandons its hostile policy [against the North] and replaces the armistice with a peace treaty," the government-run Minju Joson newspaper said in commentary carried by the official Korean Central News Agency.
North Korea wants to establish diplomatic relations with Washington to guarantee that the United States, which has 28,500 troops in South Korea, won't invade and topple Kim Jong Il's dynastic communist government.
Pyongyang cites the presence of US troops on South Korean soil as a key reason for building up its atomic weapons programme.
The United States repeatedly has said it has no intention of attacking the North, but sought to show with the drills that its solidarity with South Korea remains as strong as ever.
The exercises, dubbed "Invincible Spirit", involve about 20 ships, 200 aircraft and about 8,000 US and South Korean sailors.
Most of the firepower has been flying off the decks of the USS George Washington, a US supercarrier.
