Taliban fighters seized control of the northern Afghan provincial capital for three days last week, their most spectacular victory since being toppled from power by a US-led coalition in 2001.
General Murad Ali Murad, Afghanistan’s deputy army chief, told media Monday that Pakistan’s military had helped lead the attack.
“We will identify and detain these Pakistani generals who are hiding now and escaped wearing women’s burqas,” he said.
Pakistan was the Taliban’s main ally during their 1996 – 2001 rule and is frequently accused by Afghanistan of supporting the present insurgency.
A Pakistani military spokesman said in a statement late Tuesday the allegations of Pakistani involvement in the Kunduz attack were “mischievous”.
“The allegations levelled by an Afghan official are totally unfounded, baseless, uncalled for and mischievous,” he said. “Such allegations are not even comprehensible.”
Pakistan for its part has been demanding Afghanistan hand over hardline cleric Maulana Fazlullah, head of the Pakistani Taliban, who is believed to be hiding in eastern Afghanistan.
Hopes for better ties between the neighbours were high following the election of President Ashraf Ghani last year, who said he wanted a rapprochement similar to France and Germany after World War II.
But they have plummeted since then, with Kabul blaming Islamabad for a surge in Taliban violence this year, as Ghani accused Pakistan of sending “messages of war”.
