"At the same time I cannot vote for this resolution because it barely mentions the human suffering of the Palestinians in Gaza."

Dennis Kucinich, a Democratic congressman for Ohio who voted against the bill said before the vote: "I'm hopeful that we do not support the inhumanity that has been repeatedly expressed by the Israeli army."

"We must take a new direction in the Middle East, and that new direction must be mindful of the inhumane conditions in Gaza".

US-Israel ties

Washington has been Israel's closest ally since 1948, when Harry Truman, the former president, made the US the first country to recognise Israel.

The US has been repeatedly criticised by Arabs for its unstinting support of Israeli actions. The US frequently blocks United Nations resolutions critical of Israel and on Thursday abstained from a Security Council vote calling for a ceasefire in Gaza.

The House has passed similar measures in recent years by massive majorities.

In 2006, the House voted to condemn Hamas and Hezbollah for "unprovoked and reprehensible armed attacks against Israel" and supported Israel's incursion into Lebanon.

In 2004, the body voted to support a statement by George Bush, the US president, that it was "unrealistic" to expect Israel to return completely to its pre-1967 borders.

The US senate had voted on Thursday to back its own resolution offering "unwavering commitment" to Israel.

That recognised "its right to act in self-defence to protect its citizens against acts of terrorism" and urged a ceasefire that would keep Palestinians from firing rockets at Israel.

Harry Reid, who leads the Democratic majority in the senate, said on Thursday following that vote: "Our resolution reflects the will of the state of Israel and the will of the American people."
