The Israeli authorities said there had not yet been reports of any casualties from what the Israeli military says were Hamas rocket attacks on a number of cities.
The barrage was reportedly aimed at cities including Tel Aviv, Jerusalem and the northern city of Haifa.
"We are not getting reports of casualties from any of the impact areas," the chief military spokesman, Brigadier-General Motti Almoz, told Israel's Channel 10 television, although he did not specify where any rockets may have landed.
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.
