The Oklahoma Medical Examiner's Office says 51 people have been killed by a tornado that hit suburban Oklahoma City on Monday afternoon.

Spokeswoman Amy Elliott says the death toll is expected to rise. Elliott didn't know how many of those killed were children.

Oklahoma Gov. Mary Fallin says "hearts are broken" for parents wondering about the fate of their children after a tornado devastated suburban Oklahoma City and officials say the search and rescue effort will continue throughout the night.

Fallin told a Monday news conference that a center for those seeking loved ones has been set up at a church in Moore, where an afternoon tornado flattened entire neighborhoods and destroyed an elementary school with a direct hit. She says responders are working as quickly as they can to sort through the rubble.

Authorities who joined Fallin say search and rescue efforts are ongoing and will continue overnight.

Gov. Mary Fallin is touring the areas hit hard by tornadoes Sunday.

The governor visited Carney at 10 a.m. Monday before traveling to the Shawnee area. The governor plans to tour the Steelman Estates Mobile Home Park in Shawnee, where two people were killed.

Twenty-one people were also injured after severe weather raked the state.

A tornado kicked up debris in an Oklahoma City suburb and threatened a number of tourist attractions on historic Route 66 before growing into a larger storm that rolled across rural parts of central Oklahoma.

Television footage Sunday showed a tornado at Edmond . The storm threatened a novelty soda-pop store and a historic barn in the small town of Arcadia, then grew into a larger storm as it moved northeastward a few miles north of the Turner Turnpike between Oklahoma City and Tulsa.

OKLAHOMA CITY (AP) - State officials say Oklahoma's unemployment rate dipped below 5 percent in April.

The Oklahoma Employment Security Commission says the state's unemployment decreased by one-tenth of a percentage point to 4.9 percent last month. That remains well below the national unemployment rate of 7.5 percent.

The commission says nonfarm employment rose by 1,800 jobs in April in Oklahoma. The professional and business services sector saw the greatest increase at 1,300 jobs, while leisure and hospitality jobs dropped by 2,000.

OKLAHOMA CITY (AP) - Convicted criminals who maintain their innocence would have a way to seek DNA testing in their cases under a bill that is nearing final passage in the Legislature. The bill's passage would eliminate Oklahoma's dubious distinction as the only state in the nation without such a program.

The Oklahoma House voted unanimously on Thursday for the Postconviction DNA Act, which allows those convicted of violent felonies or who have been sentenced to 25 years or more in prison to file a motion in court to request forensic DNA testing in their case.

OKLAHOMA CITY (AP) - Gov. Mary Fallin is proposing a last-minute legislative change to the state's Insure Oklahoma program that would direct $50 million in state tobacco taxes to pay for more than 9,000 Oklahomans who are expected to lose their health insurance under the program.

Fallin released a statement Friday urging lawmakers to redirect the $50 million so the Insure Oklahoma could continue to operate as a ``smaller, more targeted program run with state dollars only.''
