WASHINGTON (AFP) - The US House of Representatives was expected to easily approve a sharply worded resolution Tuesday denouncing a UN report that Israel and Palestinian militants committed war crimes in the Gaza war.

With the UN General Assembly due to take up the Goldstone report on Wednesday, US lawmakers were set to vote on a non-binding resolution pushing President Barack Obama to repudiate and block UN approval of its findings.

"I'm going to vote emphatically for it," said Democratic House Majority Leader Steny Hoyer. "I think the UN report is unbalanced, and unfair, and inaccurate.

"It's unfortunate that the United Nations deals with Israel, in my opinion, in a totally biased and unbalanced way. And it is the only country in the world, Israel, that has a special focus by the United Nations," he added.

The resolution, crafted by Republican Representative Ileana Ros-Lehtinen, expressed support for the Obama administration's condemnation of the report and urges opposition to its findings in any international forum.

Named after former South African judge Richard Goldstone, who headed the inquiry committee, the UN report accuses Israel and Hamas militants of war crimes during the 22-day conflict that flared up in late December 2008 and ended in January, killing some 1,400 Palestinians and 13 Israelis.

Goldstone recommended that Israel and the Islamist movement Hamas -- which rules the tiny Palestinian coastal enclave -- face possible prosecution in The Hague if they fail to conduct credible investigations within six months.

Hoyer said rocket fire from Palestinian fighters in Gaza had placed Israel in "an unfortunate position" and stressed that Israel "is as careful a government as there is in terms of prosecuting its own defense" officials.
