Clinton makes unannounced visit to Kabul U.S. Secretary of State Hillary Clinton made a previously unannounced visit to Kabul on Saturday to meet with Afghan President Hamid Karzai on the eve of a donors' conference in Tokyo to pledge aid for Afghanistan. U.S. officials with Clinton declined to say how much aid the United States would pledge at the Tokyo meeting, nor how much was expected to be committed overall as the international community seeks to back the Afghan economy and prevent the country from sliding back into chaos as foreign troops withdraw. Participants are expected to commit just under $4 billion annually in development aid for Afghanistan at Sunday's meeting. Clinton was expected to have a breakfast meeting with Karzai and then visit the U.S. Embassy. Reuters contributed to this reports.
