LAUREL, Mont. (AP) - ExxonMobil and Montana's governor are at odds over the damage from an oil spill on the Yellowstone River.

ExxonMobil Pipeline Co. president Gary Pruessing says flyovers had shown most of the damage was limited to a 10-mile stretch of river. But Gov. Brian Schweitzer dismisses the claim as premature.

The Democratic governor says Exxon Mobil needs to get more personnel to inspect the situation close-up. He also slammed Pruessing's statement to reporters that no injured wildlife had been found. He says it's "silly" to make that claim at this stage.

He says a physical inspection of the river in small boats is needed soon.

A break in a company pipeline near Laurel fouled miles of riverbank and forced municipalities and irrigation districts to close intakes across eastern Montana.

Exxon Mobil has brought in more cleanup workers to mop up crude.
