North Korea boastfully threatened to strongly confront future US hostility Monday, when it marked the 49th anniversary of its seizure of the US intelligence boat Pueblo.

The 906-ton US Navy ship was captured by the North in January 1968. The North claimed the ship violated its territorial waters, while the US argued it was in international waters at the time of the attack. 

One crew member was killed in the attack, and 80 others and two civilian oceanographers were seized. All of them were freed from an 11-month captivity after the US signed a letter of apology. 

Since then, Pueblo, named after a city in Colorado, has been on display at the War Victory Hall along the Taedong River in Pyongyang for propaganda purposes.

The US should remember the shameful lesson from the Pueblo case, the North's propaganda website Uriminjokkiri said.
