It is a You Tube video available directly from You Tube. It is not from the Middle East Media Center. Just google "Israeli sniper + children" and there are a bunch of such videos, including this one.
You only use pro-Israeli sites. U.S. media is pro-Israeli, Israeli media is pro Israeli. Read some neutral media from continental Europe for once.
Like the BBC perhaps, or the Guardian. Both shown to be anti semitic and pro islam .
