The search by emergency workers for survivors in the wreckage left by the huge tornado that ripped through an Oklahoma suburb is coming to an end, according to officials.
Moore fire chief Gary Bird said he was almost certain there were no more bodies or survivors left in the rubble.
"I'm 98 per cent sure we're good," he said.
Authorities said that the full scale of the damage was not yet known, and were yet to confirm how many homes were destroyed and families displaced. Bird said that by last night each home had been search at least once. No additional survivors or bodies have been found since Monday night, Bird said.
As the frantic rescue work continued, President Obama promised that the federal government would get everything needed “right away” to victims of the devastating tornado that struck on Monday afternoon, killing at least 24 people.
“The people of Moore should know their country will remain on the ground, there for them, beside them, as long as it takes,” Mr Obama said at the White House a day after the most destructive storm in the US since the 2011 tornado in Joplin, Missouri, which killed 161 people and caused almost $3bn (£1.9bn) of damage.
“There are empty spaces where there used to be living rooms and bedrooms, and classrooms, and in time we’re gonna need to refill those spaces with love and laughter and community,” the President declared.
In fact, however, while the physical damage left by the twister, packing winds of 200mph or more, has yet to be assessed, the human toll appears to be lower than at first feared. With many people still unaccounted for, the total of 24 deaths – including nine children – may yet climb, but the final figure is likely to fall well short of earlier estimates of as many as 91.
By noon, emergency workers who had toiled through the night had pulled more than 100 survivors from the rubble of flattened homes, schools and a hospital in Moore, a town of 55,000 people 10 miles south of Oklahoma City. More than 230 people were injured, and 120 were being treated at nearby hospitals, about 50 of them children, according to local officials. Last night more bad weather in the area, including hail, heavy rain and lightning, and the risk of further tornados, was complicating the rescuers’ work.

The scale of the calamity drew sympathy from far beyond the US. The Queen and Pope Francis were among world figures who sent condolences, while in Washington, House Speaker John Boehner ordered flags on Capitol Hill to be flown at half-mast. “This was the storm of storms,” Oklahoma City mayor, Mick Cornett, said.
The devastation occurred despite what appears to have been a highly efficient performance of the local weather service, in a region known as “Tornado Alley” for the frequency of lethal storms that batter the area.
A tornado warning was in effect for 16 minutes even before the storm first touched down. That is three minutes more than the average tornado alert, allowing those threatened to take refuge in basements – or more dangerously – to drive away from a storm whose path can swiftly change.
But in the case of a monster tornado, on the ground for 40 minutes and cutting an apocalyptic swathe 20 miles long and up to two miles wide, even the most careful precautions are sometimes not enough. Monday’s storm, moreover, was a 4 on the Fujita scale used to measure a tornado’s intensity, the second highest level, with winds of 200mph or more.
“People did the right thing,” said US Congressman Tom Cole, who lives in Moore. He added that the Plaza Towers school – where seven of the nine children died – was structurally the strongest building in the area. “But if you’re in front of an F4 or an F5 there is no good thing to do if you’re above ground. It’s just tragic.”
Monday’s was the fourth tornado to hit Moore since 1998. The following year an even more powerful F5, with winds of 250mph or more, killed 36 people. A tornado also struck in 2003.
