LONG BEACH, Wash. -

Authorities say an 11-year-old girl is missing in the Pacific Ocean surf off a southwest Washington beach while her 9-year-old brother was rescued after treading water for about a half hour.

Petty Officer Third Class Jordan Akiyama said a Coast Guard air and water search for the little girl was suspended Thursday night after seven hours.

Long Beach Police Chief Flint Wright says the children had been wading in the surf in his town when they apparently got caught in a rip tide. He says the children and their mother are from Chimacum on Washington's Olympic Peninsula.

Wright called it "miraculous" that the boy was found alive.

Surf rescue team leader Doug Knutzen says the boy told rescuers he didn't know where his sister was. Knutzen says only the very top of the boy's face was out of the water when rescuers reached him. The child was treated at a nearby hospital.
