The UN Human Rights Council has adopted a resolution condemning Israel's offensive in Gaza.
The resolution accuses Israel of 'grave' human rights violations against Palestinians.
It includes setting up a fact-finding mission to investigate Israeli violations against Palestinians.
The resolution was passed despite divisions between western countries and others over its wording.
33 African, Asian, Arab and Latin American countries voted for, 13 European states abstained, and Canada was the only country to vote against.
The 47 member states in the UN's human rights assembly normally take their decisions by consensus.
The resolution released by the UN Council 'strongly' condemned the Israeli military operation in Gaza, saying it had 'resulted in massive violations' of the human rights of Palestinians.
Israeli troops have again clashed with Hamas militants in Gaza, with the most violent clashes reported in the north of the territory.
Infantry units exchanged fire with Palestinian fighters in the northern town of Jabaliya and also the southern town of Khan Yunis.
Israeli aircraft struck some 12 targets in Gaza overnight, marking the lowest level of night-time bombing since the offensive was launched.
Military sources said they struck Hamas gunmen, weapons caches, a rocket launching position and a smuggling tunnel under Gaza's border with Egypt.
Since the start of the Israeli operation on 27 December, at least 905 people have been killed, including at least 277 children, and another 3,950 wounded, according to Gaza medics.
Ten Israeli soldiers and three civilians have been killed in combat or in rocket attacks since the operation began.
The Israeli army has also begun sending in some of the thousands of reservists called up when the war began, and an army spokesman said they would be increasingly integrated into combat units.
The Israeli media speculated the move could be a sign that the offensive could intensify.
However Israeli officials have suggested the fighting might be approaching its end, despite the rejection of a UN Security Council resolution calling for an immediate ceasefire.
Troops pushed deeper into Gaza's main city overnight, as aircraft carried out nearly 60 air strikes to combat Palestinian rocket fire, which has continued despite the offensive.
15 rockets and mortars crashed inside Israel today, without causing injuries.
Earlier, Israeli Prime Minister Ehud Olmert said Israel was nearing the goals it had set for its operation, but that fighting would continue for now.
Palestinian militants have fired more than 600 rockets, some of them penetrating deeper than ever inside Israel.
The conflict has sparked worldwide pro-Palestinian demonstrations, and US president elect Barack Obama said he is assembling a team of diplomats to start addressing the Middle East conflict once he is sworn in on 20 January.
