Because it was never substantiated. There's little point in repeating information that's no more trustworthy than taking a poll of random people on the street.
Israel is free not to release their evidence, and the rest of us are free to infer what we would like from the fact that a first world nation refuses to substantiate their reasoning for bombing a news outlet.
That would stand for pretty much any nation that considers itself to be free. If Germany bombed their AP HQ and refused to release any evidence of why, there would be some very stern questions as well.
That's the excuse used to bomb every hospital, school and press building by the Zionist regime. Hard to take anything that comes out of their mouths seriously.
Why did you omit the reason for targeting?
"... because it was being used by the groups Hamas and Islamic Jihad and that terrorist attacks were directed from there"
