::::I have no idea what you are calling a BLP violation. Please be specific.  The Arab media quote was from Ynet, and seems somewhat supported by the quote from the BBC.  Other than that, there is little to no evidence that your other "massacre" names are actually official names, in common usage as a name and I am seeing from the above conversation that there is no consensus to include it.  Please check out the link to WP policy. Maximally, one can say that it is noted that it is referred to that way in the Arab press, though I don't believe it belongs in the lead at all, since we can only support that it is the Arab opinion, not international opinion.
