The Red Cross group says Israeli Defense Forces ordered one team of medics to leave before they had a chance to check all the damaged houses. The Israeli army told ABC News that it had not received a complaint from the Red Cross and would not comment on the group's press releases.
In another case, a Palestinian ambulance came under Israeli fire Thursday, as its crew tried to recover an injured civilian. The medic was shot twice in the legs, forcing the team to leave the civilian behind. Palestinians claim 12 medics have been killed while tending to the wounded since the fighting began.
Meanwhile, Israel is on tenterhooks, concerned not only about its northern border with Lebanon, but also suicide bombers.
Local television news ran alerts about a possible suicide bomber incident at a gas station outside a Jewish settlement in the Israeli-controlled area of the West Bank.
Israeli police say a Palestinian man was shot and killed at a gas station outside the settlement Ma'ale Adummin after he began pouring gas on cars at the station and refused to heed police calls to stop.
This follows the heaviest night of fighting yet. In its daily summary of activity, Israel's Defense Forces say its military hit 60 targets throughout Gaza. Smuggling tunnels and suspected weapons storage sites appeared to be the focus.
Late Wednesday evening, Israeli planes dropped leaflets in the city of Rafah, which straddles the Gaza-Egypt border, telling residents they had 30 minutes to evacuate. Heavy fighting was reported in the area throughout the night.
The renewed fighting followed a temporary cease-fire that allowed humanitarian groups to move aid into Gaza and its residents to access distribution centers. Israel allowed 80 trucks of aid to move through its border crossings into Gaza. Medical supplies were also allowed in, with several Gaza hospitals reporting that they are running low on bandages, beds and medicine. Several of the critically injured were also evacuated from Gaza into Egypt through the border crossing at Rafah.
For the first time the Israeli military allowed journalists from the BBC to accompany troops.
One Gazan said, "I came out to try to find some basic needs for my family, items that have gone away. This is the first time i left home. I used to go out of the building but there was a serious fear to leave, to come [to] downtown Gaza because they were bombing here."
When asked about the civilian casualties and the misery in Gaza, an Israeli soldier said, "You don't enjoy seeing the houses that are ruined and families that have to go out from it. But you have to remember that the Palestinians, they chose Hamas and Hamas is the terror organizations and this [is] exactly what they got."
While the fighting in Gaza grinds on, there are reports that Israel's top leadership is divided on how to proceed. Three of Israel's largest newspapers reported splits between the top three policymakers on the war -- Prime Minister Ehud Olmert, Defense Minister Ehud Barak and Foreign Minister Tzipi Livni.
News reports indicate the top leadership wants to widen the offensive, maintain it at its current level, pull out with no deal or pull out with a deal.
Barak, who has been most associated with the current campaign, was quoted in the newspaper Ma'ariv as expressing concern about the next phase of the ground campaign.
