Haven't read through yet... hopefully this is the bomb squad detonating the stuff they found in the kids' apartment.
That's what the OU Daily is reporting. They took it out to their range to detonate. It sure was loud and I am probably 4-5 miles from the site.
Yes, that's what later replies indicat. Additionally, a thread explains the huge explosive cache that was found in the apartment. Not any website but a likely credible one. I'll post the URL if I can find it.
