I don't know if the 35 includes the earlier 15 already reported (from report linked from "Link Blog" about Israel preventing help from reaching Palestinians, about an earlier block on aid and succor lasting four days) but AP report "UN halts Gaza aid shipments, cites Israeli attacks" says:
During a three-hour pause in the fighting to allow in food and fuel and let medics collect the dead, nearly three dozen bodies were found beneath the rubble of bombed out buildings in Gaza City.
Many of the dead were in the same neighborhood where the international Red Cross said rescue workers discovered young children too weak to stand who had stayed by their dead mothers.
Relations between Israel and humanitarian organizations have grown increasingly tense as civilian casualties have mounted.
Yah think?
But even more interesting is the fact that Israel got the aid shipments stopped:
The U.N. halted deliveries to the Gaza Strip on Thursday after gunfire from an Israeli tank killed an aid truck driver, and the threat of a wider conflict arose when militants in Lebanon fired rockets into northern Israel.
Huh? What would a small rocket landing 136 miles away from the top of Gaza have to do with aid shipments to the enclave. But look at the authors. It appears that reporter Ibrahim Barzak will no longer be allowed to report without the aid of an Israeli handler.
That's what happens when advertising pays most of the money for your news media.
It looks much more certain that it was the attack on the aid truck that stopped the shipments.
U.N. spokesman Adnan Abu Hasna said the U.N. coordinated the delivery with Israel, and the vehicle was marked with a U.N. flag and insignia when it was shot in northern Gaza.
...
Many of the dead found Thursday were in Gaza City's Zeitoun neighborhood, where the international Red Cross said it found four small children alive next to their mothers' bodies in the rubble of a home hit by Israeli shelling. The neutral aid group says a total of 15 dead were recovered from two houses in the Zeitoun neighborhood of Gaza City on Wednesday.
A Red Cross spokesman says rescuers had been refused permission by Israeli forces to reach the site for four days. It said the delay in allowing rescue services access was "unacceptable."
Now if the UN was like Israel or my nation (the US) they'd go attack the Jewish nation and claim every civilian death was just collateral damage while the world organization was trying to get that tank gunner that killed their man.
No wonder people think the UN is out of date. Kill Kill Kill is the new way to go.
Hey, it worked in the Dark Ages.
