因阿富汗政府的腐败问题报道，美国立法委员投票通过削减对其40亿美元的援助。

US lawmakeMr Karzai's government has faced numerous allegations of corruptionrs have voted to cut almost $4bn (£2.7bn) in aid to the government of Afghanistan, after allegations of corruption.

It comes after the Wall Street Journal reported that huge sums of cash had allegedly been flown out of Kabul international airport in recent years.

Military operations and humanitarian⁴ aid（人道主义援助） will not be affected⁵ by the cuts.

But critics fear the move could threaten crucial infrastructure⁶ projects in Afghanistan.

Meanwhile, Gen David Petraeus, who has replaced Gen Stanley McChrystal as the commander of US forces in Afghanistan, is on his way to brief US allies at Nato headquarters in Brussels.

He will then travel to Afghanistan to take up his new post, after he was confirmed by the US Senate on Wednesday.

'Lining⁷ pockets'

US Congresswoman Nita Lowey, chair of the subcommittee（小组委员会） responsible for aid appropriations⁸, has demanded that an audit⁹（审计，查账） is carried out of billions of dollars of past funds.

She said that alleged³ corruption in the Afghan government made taxpayer¹⁰ money hard to justify¹¹.

"I do not intend to appropriate one more dime¹² for assistance to Afghanistan until I have confidence that US taxpayer money is not being abused to line the pockets of corrupt¹ Afghan government officials, drug lords and terrorists," Ms Lowey said.

The money could be reinstated（恢复） in a few months after a review of Kabul's efforts to tackle the issue.

Republican lawmaker Mark Kirk, however, expressed concern that the slashing¹³（猛砍，鞭打） of funds could put important projects at risk and would not help the war effort.

He cited the example of Kandahar's electrical system, which he said was an important step to winning over the residents of the area to the US mission.

President Hamid Karzai has denied allegations of corruption by government officials, and has pledged to take a firm stance（立场，姿态） on the issue.

On Monday, the Wall Street Journal claimed that US investigators¹⁴ believed that "Afghan officials and their associates were sending billions of diverted US aid and logistics dollars and drug money to financial safe havens¹⁵ abroad".

The BBC's Jane O'Brien in Washington says that the aid cuts will send a very strong message to the Karzai government that they need to do more about corruption.

Our correspondent says that the issue is yet another blow to diplomatic relations.

Kabul has meanwhile said that international partners should shoulder some of the blame for failing to provide oversight¹⁶ for contracts, our correspondent adds.

The subcommittee has not cut military funds, which are to be debated in a separate bill.

Lawmakers are due to vote as early as Thursday on President Barack Obama's request for $33bn in military aid to support a surge of 30,000 troops.
