AP reporting on Fox. North started it. Is Kim Jong Il, having gotten the up-front goodies for promising to shut down the nuke program, fomenting yet another crisis to avoid compliance? AP notes:

The shooting comes a day ahead of working-level talks to agree on the details of an aid-for-disarmanent deal with Pyongyang in the truce village of Panmunjom that separates the two Koreas.
North Korea has already received 50,000 tons of heavy fuel oil from Seoul in return for the shutdown of its sole operating nuclear reactor and accepting inspections by the International Atomic Energy Agency.
The energy-starved North is to eventually get further economic incentives equivalent to 950,000 tons of heavy fuel oil in return for irreversibly disabling the reactor and ending all nuclear programs, but has yet to set a deadline.

Naaahhh. Probably just a coincidence.
