The Pakistani prime minister's adviser on foreign affairs is hoping that a long-stalled four-nation peace process aimed at ending the war between Kabul and the Taliban could be revived in the coming weeks.

Sartaj Aziz told reporters Friday that the lingering violence in Afghanistan could only end through the revival of peace talks.

He also said the "Taliban cannot capture Afghanistan" through violence, although Kabul believes Pakistan is still backing the Taliban.

The four-nation peace process has been on the hold since May 21 when a U.S. drone attack killed the Taliban chief Mullah Akhtar Mansour in Pakistan, days after Pakistan, Afghanistan, China and the United States met in Islamabad and vowed to continue their efforts.

Pakistan has said Mansour's killing scuttled the peace process.
