Both the US and the Taliban agree to sign an accord on February 29 in Doha, following the one-week partial truce
A week-long partial truce came into effect across Afghanistan early Saturday, with the Taliban, the US and Afghan forces all signed up to a lull that could be a turning point in the long conflict.
If the so-called "reduction in violence" holds, it will be a major step towards withdrawing US troops after more than 18 years -- and launching Afghanistan into an uncertain future.
Both US Secretary of State Mike Pompeo and the Taliban issued statements saying they had agreed to sign an accord on February 29 in Doha, following the one-week partial truce.
"Upon a successful implementation of this understanding, signing of the US-Taliban agreement is expected to move forward," Pompeo said, adding that talks between the Taliban and the Afghan government would "start soon thereafter."
Afghanistan's National Security Council spokesman Javed Faisal and Taliban sources said a "reduction in violence" between US, Taliban and Afghan security forces had been agreed.
The United States has been in talks with the Taliban for more than a year to secure a deal in which it would pull out thousands of troops in return for Taliban security guarantees and a promise to hold peace talks with the government in Kabul.
A reduction in violence would show the Taliban can control their forces and demonstrate good faith ahead of any signing, which would see the Pentagon withdraw about half of the 12,000 to 13,000 troops currently in Afghanistan.
Afghan President Ashraf Ghani said Friday that the partial truce would start at midnight.
"Our next steps on the peace process will depend on the evaluation of the week of the reduction in violence," Ghani, who this week secured a second term in office, said in a televised address.
"The Afghan security forces will remain on active defence status during the week".
In a statement, the Taliban said warring parties would "create a suitable security situation" ahead of a deal signing.
The Taliban's political spokesman, Suhail Shaheen, separately tweeted that the agreement would see "all" foreign forces leave Afghanistan.
But a senior US administration official stressed that any withdrawal would be "conditions based."
For now at least, the US wants to leave troops in Afghanistan on a counter-terrorism mission to fight jihadists such as the Islamic State group.
The reduction of US forces "is very much tied to delivery on the commitments that (the Taliban) have made," the US official told reporters.
One Taliban source in Pakistan said that if an agreement was signed February 29, talks between the Taliban and the Afghan government, needed to cement a broader peace deal, would be slated to start on March 10.
The international community hailed the announcement, with Nato saying the deal could make way for "sustainable peace," while Russia labelled it an "important event" for the ending the war.
Pakistan, which helped facilitate the talks between the US and the militants, also welcomed the news.
In southern Kandahar province, which is seen as the Taliban's heartland, one insurgent told AFP he had received orders to stand down.
But another Taliban commander based in Kandahar, Hafiz Saeed Hedayat, said he had only been ordered to refrain from attacking major cities and highways.
"This means maybe the violence will continue in the districts," Hedayat said.
Taliban expert Rahimullah Yusufzai said the move signalled a change in thinking for both the Taliban and the US after years of fighting.
"Both sides have shown their commitment to sign the peace deal, and it's a big development," he said.
The US and the Taliban have been tantalizingly close to a deal before, only to see President Donald Trump nix it at the eleventh hour in September.
The attempt to stem Afghanistan's bloodshed is laced with complications, including the fear that competing forces could exploit a lull to secure a battlefield advantage.
The reduction in violence is "still just the first step," Andrew Watkins, a senior analyst with the International Crisis Group, told AFP.
"Those talks will be a tough road of their own, but are the best avenue to peaceful settlement to Afghanistan's conflict."
On Thursday, the deputy leader of the Taliban said the insurgents were "fully committed" to a deal with Washington.
"That we stuck with such turbulent talks with the enemy we have fought bitterly for two decades, even as death rained from the sky, testifies to our commitment to ending the hostilities," Sirajuddin Haqqani wrote in an opinion piece in The New York Times.
Haqqani is also head of the Haqqani network, a US-designated terror group that is one of the most dangerous factions fighting Afghan and US-led Nato forces in Afghanistan.
Since the US-led invasion of Afghanistan after the September 11, 2001 attacks, America has spent more than $1 trillion in fighting and rebuilding in Afghanistan.
About 2,400 US soldiers have been killed, along with unknown tens of thousands of Afghan troops, Taliban fighters and Afghan civilians.
