Israel is fully aware of the building that houses most of the media, plus some families in Gaza. Two notable media organisations were based in the building. Al-Jazeera is a kick-ass highly respected Middle East News service. Associated Press is one of two of the most highly respected news wires (an agency that provides other news sources with news) in the world. Associated Press is an American non-profit based in New York.
Which makes the attack, all the more extraordinary!
