Absolutely true that different media outlets are presenting different/skewed versions of the truth - as happens in pretty much every political situation and war both domestically and internationally.

BBC are more impartial than most, I would argue, but hard to deny that they have been more supportive/defensive of Israel.
But that doesn't autmatically mean that what people are saying on the internet which isn't being reported by BBC is automatically true.

Good summary ath the Wiki page below about the misinformation flowing from both sides.
