Israeli ground forces are to strike Palestinian militant sites throughout the Gaza strip, a military spokesman said.
According to Reuters, the spokesman added that the escalation did not aim to topple Hamas rule.
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.
