Oklahoma tornado aftermath: LIVE UPDATES

In the aftermath of a massive tornado that killed at least 24 people on the outskirts of Oklahoma City, rescue workers are racing against time to find missing people - some of them children trapped under the rubble of their schools.

18:20 GMT: Two infants were among the 24 people killed by the tornado, said the Oklahoma medical examiner's office. 4-month-old Case Futrell and 7-month-old Sydnee Vargyas  died from head injuries. It also raised the death toll of children from nine to ten. The eight other children ranged in age from 4 years old to 9 years old. Of those, six suffocated and two died from massive injuries. Elliott said the agency still is trying to determine the ages of five of the victims.

"The ME staff worked throughout the night and yesterday in coordination with state and federal agencies to identify victims and document injuries," medical examiner's spokesman Amy Elliott said in a statement.

18: 18 GMT: President Barack Obama will visit the tornado-ravaged site and meet with victims and first responders on Sunday according to White House spokesman Jay Carney.

18:16 GMT: 12,000 to 13,000 homes were affected by the tornado said Oklahoma City Mayor Mick Cornett. The financial cost of the tornado could exceed $2 billion, because of the size and duration of the storm, according to the Oklahoma Insurance Department. 

02:15 GMT: A spokesman for the state Department of Emergency Management has cited 2,400 damaged homes within Oklahoma City and Moore. Some 10,000 people have been directly impacted by the EF-5 tornado on Monday.

01:10 GMT: Moore's community center is seeking donations of flashlights, batteries and lanterns for those residents left without power. There's also a need for tetanus shots, for those who have stepped on nails embedded in debris while working outside.

23:30 GMT: Some 34,000 customers in Oklahoma remained without power on Tuesday evening, according to a report by the state's Department of Emergency Management.

22:50 GMT: Mayor Glenn Lewis said late Tuesday afternoon that "we don't have anybody missing," referring to tornado rescue and recovery efforts in his city.

22:12 GMT: Albert Ashwood, director of the Oklahoma Department of Emergency Management, told reporters on Tuesday that neither of the two schools torn apart by Monday’s EF-5 tornado in Moore, Oklahoma had reinforced tornado shelters.

In apparent dispute of that information Moore's mayor, Glenn Lewis said, Briarwood Elementary School had no fatalities as it was a "newer model" of schools and had a "safe room."

According to Ashwood, more than 100 schools across the state have such emergency shelters, though it is up to each jurisdiction as to whether limited funding is used for these safe rooms and at which schools.

The official added that a shelter would not have necessarily saved more lives at the Plaza Towers Elementary School, where children sought shelter above-ground classrooms.

Authorities will review which schools have safe rooms, and try to implement them in additional schools, said Ashwood.

During an afternoon press conference, officials in Moore, OK offered an update on the situation on the ground less than a day after a devastating tornado ripped through town.

Gov. Mary Fallin remarked that the May 20 twister was “one of the most horrific storms” to ever hit the state, but insisted that the city will be able to pick itself up thanks to expedient rescue efforts already underway.

“We will get through this. We will overcome, we will rebuild and we will regain our strength,” the governor said.

But although Gov. Fallin is optimistic about the relief efforts seen so far, she admitted that authorities are still assessing the damages caused by what Oklahoma City, OK Mayor Mick Cornett called “the storm of storms.”

Fallin said that 237 people have been reported injured, but cautioned, “Frankly, we don’t even know yet if there are missing people” still hoping to be rescued.

Officials have so far put the death toll at 24, but just before 6 p.m. GMT the governor said, “We don’t have any firm numbers.”

Craig Fugate, an administrator with the Federal Emergency Management Agency said, “We’re going to keep looking until everybody is found” and encouraged residents of Oklahoma to apply for relief from FEMA.
