Peace talks between Afghanistan and Pakistan have broken down, although a ceasefire continues between the South Asian neighbours, a Taliban spokesperson says.

Zabihullah Mujahid said negotiations had failed due to Islamabad insisting that Afghanistan assume responsibility for Pakistan's internal security, a demand he described as beyond Afghanistan's "capacity".

But, he said, "The ceasefire that has been established has not been violated by us so far, and it will continue to be observed."

On Friday, Pakistani Minister of Defence Khawaja Muhammad Asif said peace talks with Afghanistan in Istanbul aimed at preventing renewed border clashes had collapsed, adding that the ceasefire would hold as long as there were no attacks from Afghan soil.
