朝鲜半岛南北过境点在平壤切断热线后仍运作

A tense border crossing between North and South Korea was operating as usual Thursday, despite Pyongyang cutting a crucial communications link that helped coordinate passage at the border.

The North on Wednesday cut its last military hotline with Seoul, saying it was no longer necessary since "war may break out at any moment." The phone was also used to arrange passage for South Korean workers at a joint industrial complex in the North.

Pyongyang has in the past cut the military hotline, stranding South Korean workers at the complex. But workers ((such as this truck driver Park Chul-hee)) reported business as usual at the Kaesong industrial complex Thursday.

Tensions on the Korean peninsula are at their highest in years, with both the North and the U.S.-backed South demonstrating their military preparedness.

In the latest show of force, the U.S. Armed Forces Korea said two B-2 stealth bombers conducted a live-fire training mission over the South Thursday. A statement said the nuclear-capable bombers flew over 10,000 kilometers from a midwestern U.S. base to the Korean peninsula, conducted the firing drill, and returned to the continental U.S. in a "single, continuous mission."
