Israel has brought an eighth missile interceptor battery into service to counter rocket fire from Gaza, a Defence Ministry official told Israel Radio.
They said: "In the past week we have carried out a very complex technological exercise to deliver the eighth system. We brought together all the components from the production line and within days we made it operational."
He added that a ninth could be made ready within days.
"We try always to be one step ahead of the enemy... and we see that its capabilities exceed our expectations," they 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.
