Osama bin Laden, mastermind of the 9/11 attacks, is dead.
It's a huge victory for American President Barack Obama.
The relatives of his victims must also feel there has been justice. But this does not only impact Americans.
Aleksandr Ivantsov was from Siberia.
Aracelia Castillo was from Colombia.
Mohammad Salman Hamdani was from Pakistan.
You can read about them and other 9/11 victims in the New York Times' "Portrait of Grief" series.
There also were 67 Britons killed on 9/11, according to the Telegraph.
There also were dozens of 9/11 victims who were Muslim. President Obama reminded us of this fact and that we are not at war with the Muslim people who are overwhelmingly peaceful.
It's not known exactly how many 9/11 victims were undocumented but certainly they also were among those who perished. Some of them worked at the Windows on the World restaurant.
There were 14 undocumented spouses and children of workers killed at the Twin Towers who sought permanent residency after the attack, according to the New York Times.
Beyond the United States, more than 200 people were killed in the 1998 embassy bombings by Al-Qaeda in Kenya and Tanzania.
On Monday, relatives of victims gathered at a memorial garden in Nairobi just as they did at Ground Zero in New York.
In Spain, relatives of victims of a train bombing in Madrid in March 2004 are marking the death of bin Laden. More than 190 people were killed and it was traced back to supporters of bin Laden.
The wrath of bin Laden was global. Many people around the world are rejoicing that he is dead.
As Americans, we also should be aware that not everybody is celebrating. There are those who still support bin Laden and they may try to avenge his death.
There also are some who would rather have seen bin Laden go on trial than be killed. But we don't know if he could have been captured alive.
Some outside the United States see our reaction as bloodthirsty. I was watching the Al Jazeera broadcast online Monday afternoon and one commentator questioned a photo of an American child celebrating bin Laden's death.
But this commentator didn't lose friends or family on 9/11. I too might want vengeance if it were my family.
I agree with this quote from Mark Twain that has been circulating on Twitter and Facebook.
"I've never wished a man dead, but I have read some obituaries with great pleasure."
