An Israeli air strike killed six Hamas militants the Hamas armed wing said, in what would be the biggest single hit against the Islamist group since an eight-day war in 2012.
The Israeli military had no immediate comment on the reported attack which came after at least a dozen rockets were fired at southern Israeli towns and cities on Sunday.
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.
