Afghan officials are pushing to create a "safe zone" for Taliban insurgents in a bid to wean them away from traditional sanctuaries inside Pakistan, in a radical and contentious strategy to de-escalate the conflict, AFP reports.

The plan underscores desperation in Afghanistan for out-of-the-box solutions to tackle the 15-year insurgency, as peace bids repeatedly fail and U.S.-backed forces suffer record casualties in stalemated fighting.

If implemented, the strategy -- aimed at undercutting Pakistan's influence over the Taliban -- could, for better or for worse, be a game changer in a strife-torn nation where ceding territory to insurgents is seen as tantamount to partition.

"I urge the Taliban to return to Afghanistan. We should make a safe zone for them and their families," Kandahar police chief Abdul Raziq told a gathering of religious scholars and tribal elders last month.

"We can no longer rely on foreign governments and embassies to end the war. The Taliban belong to this country, they are sons of this soil."

That Raziq, arguably the most powerful commander in southern Afghanistan and long one of the staunchest anti-Taliban figures, would suggest such an idea amplified the shockwaves it created.

"The government shouldn't be giving safe zones to terrorists," warned former Helmand governor Sher Mohammed Akhundzada, while some observers dismissed the strategy as "illogical" as the Taliban already control vast swathes of Afghan territory.

Raziq did not respond to repeated requests for an interview, but a senior security official told AFP the government's goal "is to bring the Taliban from Pakistan to Afghanistan".

"We will separate a territory for them to come with their families. Then whether they want to fight or talk peace, they will be relieved from the pressure of Pakistan," he said, speaking anonymously.
