U.S. President Barack Obama looks through binoculars to see North Korea from Observation Post Ouellette in the Demilitarized Zone on Sunday.

NBC News reports: SEOUL -- While at the DMZ, the president spoke to South Korean troops, then went to Observation Post Ouellette, the closest post overlooking the demarcation line on the most heavily guarded border in the world.

The observation post is about 25 miles northwest of Seoul inside the DMZ and just 100 yards from demarcation line. The North Korean army is visible from this observation post and it was expected that the North Koreans would jam cell phone signals while the president was visiting the area.
