JUDY WOODRUFF, CNN CORRESPONDENT: A day before Afghanistan's new interim government is scheduled to take power, a United Nations peacekeeping force is already in Kabul. CNN's Harris Whitbeck there is, too.</s>HARRIS WHITBECK, CNN CORRESPONDENT: The first contingent of British troops that will be part of the multinational security force in Afghanistan, arrived in the country late last night. There were 53 Royal Marines aboard a C-130 military transport plane. These Marines had been stationed on a British warship in the Arabian Sea. They traveled by helicopter to an undisclosed Middle Eastern country, and then arrived in Afghanistan late last night. They deployed from Bagrham air base this morning. They arrived into the streets of Kabul -- this was first time since 1989, since the Soviet withdrawal from Afghanistan, 1989, that foreign troops had been seen, on streets of Kabul. So it certainly was a defining moment for Afghanistan. The troops are based at the British Embassy, and their work will begin in earnest on Saturday, when they will be charged with providing security and stability for the installation of the new government. Hamid Karzai will be installed as the country's interim prime minister Saturday morning. There will be thousands of dignitaries from many countries attending the ceremony and there's a lot of expectation among the citizenry of Afghanistan about what this new government might do to ensure their future. Harris Whitbeck, CNN, Kabul, Afghanistan.
