SEOUL, South Korea (AP) — When a South Korean ferry sank with hundreds trapped inside last month, the whole world knew about it. But in North Korea, there was utter silence about the collapse of a 23-story apartment building for five days, until state media issued a rare apology.

The North is not a black hole for information. More than 2 million people have cellphones. Hundreds of foreigners live in Pyongyang, the showcase capital where the collapse occurred a week ago Tuesday. A handful of international news bureaus, including The Associated Press, operate there, and the city sees a steady procession of visiting tourists, academics and diplomats.
