Talks between Afghanistan and Pakistan in Istanbul to broker a long-term truce have ended without a resolution, two sources familiar with the matter said on Tuesday, a blow for peace in the region after deadly clashes this month.

Axar.az informs, citing Reuters, the talks aimed to reach lasting peace between the South Asian neighbors after dozens were killed along their border in the worst such violence since the Taliban took power in Kabul in 2021.

Both agreed to a ceasefire brokered in Doha on October 19, but could not find common ground in a second round of talks mediated by Turkiye and Qatar in Istanbul, Afghan and Pakistani sources briefed on the issue said, with each blaming the other for the failure.

A Pakistani security source said the Taliban had been unwilling to commit to rein in the Pakistani Taliban, a separate militant group hostile to Pakistan that Islamabad says operates with impunity inside Afghanistan.

An Afghan source familiar with the talks said they had ended after “tense exchanges” over the issue, adding that the Afghan side said it no control over the Pakistani Taliban, which has launched attacks against Pakistani troops in recent weeks.

On Saturday, Pakistan’s defense minister said he believed Afghanistan wanted peace but that failure to reach an agreement in Istanbul would mean “open war.”
