One Israeli civilian has been killed by fire from Gaza. A statement from the Israeli military said the operation will include "infantry, armoured corps, engineer corps, artillery and intelligence combined with aerial and naval support."
Palestinian health officials say 233 Palestinians have been killed in Israeli air and naval strikes, while Israeli military says Gaza militants have fired more than 1,300 rockets into Israel.
Before dawn about a dozen Palestinian fighters tunnelled under the border, emerging near an Israeli community. At least one was killed when Israeli aircraft bombed the group, the military said.
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.
