ISLAMABAD Fearing a tough response to Pakistans letter rejecting most of the findings of the UN Commission that investigated Benazir Bhuttos slaying, the Government has instructed its Ambassador to the world body to ensure that the UN doesnt react too strongly, sources in the Foreign Office informed Tuesday.
