WASHINGTON (Reuters) - U.S. Defense Secretary Chuck Hagel told lawmakers on Wednesday that a limited military strike against Syria was expected to cost "tens of millions" of dollars.

"We have looked at the different costs, depending on the different options," Hagel told a hearing in the House of Representatives. "It would be in the tens of millions of dollars, that kind of range."

Pentagon officials previously had not disclosed cost estimates for a military operation, but a Pentagon spokesman said on Wednesday that it could probably be funded with existing Defense Department resources without a request for supplemental funding.
