Book claims Sharif was unaware of Pak's Kargil infiltration

'From Kargil To The Coup', written by Nasim Zehra, has claimed that former Pakistan PM Nawaz Sharif was unaware of the Army's operation to infiltrate key positions in the Kargil sector which began in January 1999. The Pakistan Army, then headed by Pervez Musharraf, informed about the operation in May, only when he was confronted by Sharif.
