(CBS News) GAZA CITY - The battle over Gaza between Israel and Hamas escalated Sunday, with civilians suffering the most.
Palestinian health officials say an Israeli missile strike in Gaza City killed 11 civilians.
In all, at least 70 Palestinians and three Israeli civilians have died so far.
Hamas fired 100 missiles on Israel Sunday, 30 of which Israel says it shot down.
And an Israeli envoy arrived in Sunday for truce talks.
In Gaza City, rescue teams struggled in a frantic effort to reach a woman trapped under the rubble of a building leveled by Sunday's airstrike.
Palestinian officials said seven members of one family died in this attack alone, including four children.
The Israeli military says its strikes are surgical, and are finding their targets. But in one of the most densely populated places on the planet, civilian deaths are mounting.
Journalists in Gaza have found themselves in the crosshairs of Israeli missiles too.
The Israeli military released a video of a missile strike on a media center in Gaza City. Officials called it a legitimate target.
"This media building had an infrastructure of Hamas electronics communications on the roof, and we attacked that communication center on the roof," Israeli Army spokeswoman Lt. Col. Avital Leibovich:
The building which houses offices used by foreign journalists -- including CBS News in Gaza -- also came under attack early this morning.
Hamas kept up its attacks on Israel too, launching rockets from inside Gaza from this morning and into the night with another attempted attack on Tel Aviv.
Palestinians told us the past 24 hours has been the most intense in terms of attacks since fighting began five days ago.
And Sunday night they're bracing for worse to come.
There have been several explosions late Sunday night, and the constant sound of drones in the air never stops. Five or six rockets have also been launch from Gaza this evening.
