Florida ? Eleven explosions rocked the neighborhoods around Odyssey Middle School on Monday afternoon as Army Corps of Engineers detonated dozens more bombs and rockets unearthed on the school grounds during the Martin Luther King holiday weekend.

The destruction of the most recent cache of munitions at the southeast Orlando school signaled the end of the search for World War II ordnance there, Army Corps officials said.

But the Corps is not giving the school property, built on a former Army bombing range, the all-clear yet. Corps experts will return in the spring to test the soil for toxic chemicals, officials said.

In all, 53 fragmentation bombs, 10 rocket warheads, two rifle grenades and some miscellaneous rockets and charges were detonated Monday, while the school was closed for the King holiday.
