ISLAMABAD: Sources claimed on Friday that a secret CIA office existed in Abbottabad which provided key intel to the CIA headquarter about Osama bin laden’s compound for US military operation that killed Bin laden, DawnNews reported.

Reliable sources told DawnNews that contacts between CIA and Pakistani ISI had discontinued after April14.
