Reactions are pouring in from around the world to the shooting of 11 police officers — 4 of whom are dead — at a Black Lives Matter protest in Dallas. On Twitter, some blamed President Barack Obama while others simply prayed for peace.

It is TIME to shut down #BlackLivesMatter terrorists. You have done ONLY HARM. #PrayersforDallas

I have a sinking feeling that Barack is smiling his smug little smile, knowing what happened in Dallas tonight.

I keep imagining the worst thing that could happen. And then the next revelation out of Dallas blows past that.

Dallas now is as heartbreaking & cruel & soulless as all the other bloodletting. The churn of our seething, gun-saturated American abattoir

There is a special place in hell reserved for those who engage in this kind of violence at a righteous protest. #Dallas
