The Bureau of Land Management is going nationwide with its review of off-road racing events it permits on public lands.

BLM Director Bob Abbey announced the action Friday, a week after eight spectators were killed and 10 injured at a race on BLM land in California's Mojave Desert.

That tragedy initially spurred a review of racing permits in the BLM's California desert district, but the agency will now look at its permits throughout the country.

Abbey says the agency has launched an internal review of the accident and will take a close look at all approved permits and pending requests on a case-by-case basis.

The agency also says it will be increasing the BLM's presence at all such events.
