"There was no malice behind it but I was stupid," admitted actor Jason Biggs, speaking out about his tasteless remarks on the plane that was shot down over the Ukraine.
"It was offensive, it was poorly timed," Biggs said.
The day of the disaster, the Orange Is the New Black and American Pie star tweeted: "Anyone wanna buy my Malaysian Airlines frequent flier miles?"
Appearing on The View Monday, Biggs said he regretted the wisecrack.
"I didn't think and I wasn't aware of what was sort of happening and transpiring and the extent to just how horrible this tragedy is," said Biggs.
He was not the only one apologizing for showing extraordinary insensitivity to the tragedy.
A TV reporter from Britain's Sky News triggered outrage by going through a dead passenger's luggage.
"We shouldn't be doing this, I suppose really," said the reporter.
Sky News bosses later said they "apologize profusely for any offense caused."
And in bizarre moment, two WWE stars, who play Russian characters, were accused of working the Malaysia Airlines tragedy into their routine.
"You blame Russia for recent events?" said a WWE performer.
But the WWE said the routine was "In no way referring to the Malaysia Airlines tragedy. WWE apologizes to anyone who misunderstood... and was offended."
Secretary of State John Kerry expressed dismay over the way the bodies are being treated by the pro-Russian rebels who control the crash site.
"There are reports of drunken, Separatist soldiers unceremoniously piling bodies into trucks," said Kerry.
The victims' remains were being kept on a refrigerated freight train, and the worry was that the bodies are being held hostage for political reasons.
One mom from the Netherlands, who lost her son and his girlfriend, appealed directly to Russian President Vladimir Putin.
"Mr. Putin, send my children home," said the mother in a video.
Another video apparently showed a pro-Russian separatist removing the plane's black box from the crash site.
President Obama issued this warning: "The burden now is for Russia to insist that the Separatists stop tampering with the evidence, grant investigators who are already on the ground immediate, full, and unimpeded access to the crash site."
