Israel has deployed ground troops inside Gaza to raid a rocket launching site in the Palestinian territory.
It was the first time that Israeli ground troops are known to have entered Gaza in the current offensive.
But the operation, carried out by special forces, did not appear to be the beginning of a broad ground offensive.
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.
