I guess not strictly news - but with all of the vitriol I have seen in discussions on the Israel situation, that have boiled down to arguments over wording, I feel that this take from the BBC is worthy of some discussion.

The articles I have seen that refer to it as terrorism, tend to be from local BBC services, rather than the national one.
