pray for paris

On Friday, Nov. 13, more than 120 people died as the result of a series of gun and bomb attacks across Paris.

The world watched as news of the attacks made its way from the French capital.

For a sense of scale, yesterday's events marked the deadliest attack on European soil since the 2004 Madrid train bombings that killed 191 and left 1,841 injured.

Facebook moved quickly, enabling its new "Safety Check" feature, aimed at helping people near the attacks let their friends and family know they're safe.

On Saturday morning, a man played John Lennon's "Imagine" on a piano outside the Bataclan theater.

A large crowd gathered to listen his performance of Lennon's 1971 classic outside the theater where at least 87 people were killed in the Friday night attack.

The morning after the attacks, crowds in Paris lined up to donate blood.

With more than 200 people hospitalized in the wake of the attacks, it's heartening to see people so ready to help in whatever way they can.

In times of chaos and destruction, it's important to believe in the power of human kindness.

These types of attacks are meant to disrupt. These types of attacks are meant to provoke the world. In these times, it's crucial we look at those who refuse to respond out of hatred or vengeance, but instead with a message of love and peace.
