ITV News Diplomatic Correspondent John Ray reports from Israel:
Israel is saying it is expanding its operation by land sea and sky. Artillery barrage reported by colleagues in Gaza
If this is land incursion likely to be limited. Perhaps to close down Hamas tunnels. Even so, no such thing as a risk free invasion.
It's been an emotionally exhausting day in Israel and Gaza as hopes for peace were raised then dashed then raised then dashed again.
In the court of international opinion, this is how Israel wins a battle and still manages to lose the war.
Until the Israelis and the Palestinians find a way of resolving the underlining conflict this will not be more than a pause.
