Daoud hosted General Secretary of the National Awami Party Khan Abdul Wali Khan, Ajmal Khattak, Juma Khan Sufi, Baluch guerrillas, and others. Khan's government and forces also commenced training Pakhtun Zalmay and young Baluchs to conduct militant action and sabotage in Pakistan. The campaign was significant enough that even one of Bhutto's senior colleagues, minister of interior and head of the provincial branch of Bhutto's party of/in the then-North-West Frontier Province (renamed Khyber Pakhtunkhwa in 2010), Hayat Sherpao, was killed, ostensibly on the orders of the later-acquitted Awami Party. As a result, Afghanistan's already strained relationship with Pakistan further dipped and Pakistan likewise started similar kinds of cross-border interference.
