ISLAMABAD: Defence officials said Monday that the United States has assured Pakistan that Tehreek-i-Taliban (TTP) chief Mullah Fazlullah would either be arrested or killed in Afghanistan, adding that in case of an arrest he would be subsequently handed over to Pakistan.

Briefing a Senate Defence Committee in Islamabad, defence officials said that during his long visit to the US, Chief of Army Staff (COAS) Gen Raheel Sharif had also presented vital evidence of Indian involvement in subversive activities in Pakistan by using Afghan soil to top US intelligence and defence officials.

Fazlullah was elected TTP commander in November 2013, following the death of former leader Hakimullah Mehsud.

Under the leadership of Fazlullah, TTP claimed responsibility for the December 16, 2014 attack on a school in Peshawar that resulted in the deaths of at least 150 people, mostly students.
