The Hague - Afghanistan's president, Hamid Karzai, came under intense western pressure yesterday to scrap a new law that the UN said legalized rape within marriage and severely limited the rights of women.

    At a conference on Afghanistan in The Hague, Scandinavian foreign ministers publicly challenged the Afghan leader to respond to a report on the new law in yesterday's Guardian, and the US secretary of state, Hillary Clinton, was reported to have confronted Karzai on the issue in a private meeting.

    At a press conference after the meeting, Clinton made clear US displeasure at the apparent backsliding on women's rights. "This is an area of absolute concern for the United States. My message is very clear. Women's rights are a central part of the foreign policy of the Obama administration," she said.

    The Guardian reported that Karzai had signed the controversial law last month. The text has not yet been published but the UN, human rights activists and some Afghan MPs said it included clauses stipulating that women cannot refuse to have sex with their husbands, and can only seek work, education or visit the doctor with their husbands' permission.

    International aid officials say the law violates both UN conventions and the Afghan constitution. It is widely seen as a political ploy by Karzai to win support from conservative Muslims in presidential elections scheduled for August.

    Mark Malloch Brown, Britain's foreign office minister for Africa, Asia and the UN, expressed "dismay" over the law's impact on women's rights. "We are caught in the Catch-22 that the Afghans obviously have the right to write their own laws," he said. "But there is dismay. The rights of women was one of the reasons the UK and many in the west threw ourselves into the struggle in Afghanistan. It matters greatly to us and our public opinion."

    Malloch Brown did not meet Karzai yesterday, but said "one can confidently assume" that it came up in the private bilateral sessions the Afghan leader held with western officials in the course of the day. Diplomatic sources said later that women's rights had been one of the subjects of the Clinton-Karzai meeting.

    At the Hague conference, instigated at Washington's request to rally international support for Obama's new strategy in Afghanistan, Finland's foreign minister, Alexander Stubb, called on the Karzai government to respond to the Guardian report, a call echoed by Iceland, while Norway also expressed concern over the trend in women's rights.
