"broadcasted" is correct - it is an error to split it.
Some unfortunates have been passed through its horrifying experiences
"been" is incorrectly used. The sentence should read "Some unfortunates have passed through [experienced/suffered] its horrifying experiences..."
The rage of the terrorists make no differences among the people while killing them. This sentence is also badly written. The terrorists' [rage/fury/anger] allows for no differences in the people who are being killed.
Whatever this piece is, it was not written by a skilled writer of English.
