In the wake of the tornado that devastated Oklahoma, professional athletes took to Twitter to express their support for the victims.

Oklahoma City Thunder's Kevin Durant tweeted his well wishes on Monday, in addition to posting donation links to the Red Cross.

Washington Nationals' Bryce Harper, who played on a high school travel baseball team in West Moore, sent out prayers for the victims.

Even the Black Mamba expressed his sympathies and offered his followers the number to text donations to the Red Cross.

James Harden, who spent his first three seasons in OKC, and veteran NBA player Derek Fisher, who played there last season, tweeted their support.

The massive, 2-mile wide tornado blasted through Moore, a city outside Oklahoma City, on Monday afternoon. The damage was severe.  Buildings were reduced to rubble and trapped victims beneath.  Entire neighborhoods were destroyed, according to Reuters.

Plaza Towers Elementary School sustained a direct hit from the hurricane, which killed seven children there. Oklahoma State Police said they were lifting up fallen walls to free kids from the rubble.

The latest report from the Oklahoma state medical examiner's office said that 24 bodies have been recovered. More than 100 people were rescued alive from the wreckage, and authorities believe there are more survivors out there.

"We are absolutely positive that there are still people that could be trapped under the rubble and in shelters," Oklahoma Highway Patrol spokeswoman Betsy Randolph said.

President Barack Obama declared a major disaster area in Oklahoma and is sending federal aid to help the rescue efforts.  Obama said, "The people of Moore should know that their country will remain on the ground there for them, beside them, as long as it takes."
