Afghanistan's foreign minister says he believes fugitive al-Qaida and Taleban leaders are hiding across the border in northwest Pakistan.
In an Associated Press interview Sunday, Foreign Minister Abdullah said that much more effort should be made to track down Osama bin Laden and former Taleban leader Mullah Omar.
Separately, U-S Central Command General Tommy Franks says he has seen no convincing proof Osama bin Laden is dead. General Franks says if the al-Qaida leader is alive he will be caught.
Meanwhile, Afghan security officials are working to identify suspicious chemicals seized from a house in Kabul on Saturday that was previously occupied by a Saudi charity.
Officers found 16 different kinds of chemicals in the raid, along with some explosives and a pile of documents. The house in Kabul's Wazir Akbar Khan neighborhood was used by the Saudi charity Wafa until the overthrow of Afghanistan's Taleban rulers late last year.
Wafa was involved in pre-September 11th construction and food distribution projects in Afghanistan. U-S authorities suspect the charity may have links to Osama bin Laden's al-Qaida network.
Meanwhile, a bomb inside a trash can exploded Sunday outside the United Nations guest house in the Afghan capital, injuring two people. The U-N guest house, where at least 45 people are living, was not damaged.
