PORT HUENEME, Calif. (AP) — Hundreds of migrant children will be housed at a naval facility in California amid a spike in the number of youngsters caught crossing the border alone.

Vance Vasquez, a spokesman for Naval Base Ventura County, said Tuesday that a 42,000-square-foot building at Port Hueneme will provide temporary shelter.

Vasquez says the facility was remodeled in 2007 to house reservists before they deployed overseas, and has been closed for more than a year.

The base says there's bed space for about 570 people. Officials say children could start arriving this week.

The federal government is also housing migrant children at a military base in Texas. Officials estimate as many as 60,000 children, mostly from Central America, could be caught at the border this year.
