David Cameron has issued a direct appeal to the Taliban to enter peaceful talks on the future of Afghanistan after hosting talks at Chequers with Afghan President Hamid Karzai and Pakistani President Asif Ali Zardari today.
The Prime Minister said the two leaders had agreed "an unprecedented level of co-operation".
He said they had agreed to sign up to a strategic partnership between their two countries in the autumn.
At the same time, they also agreed to the opening of an office in the Qatari capital Doha for negotiations between the Taliban and the Afghan High Peace Council.
Mr Cameron said the agreement should send a clear message to the Taliban.
"Now is the time for everyone to participate in a peaceful, political process in Afghanistan."
"This should lead to a future where all Afghans can participate peacefully in that country's political process."
Ahead of tonight's talks between Prime Minister David Cameron, Afghan president Hamid Karzai and Pakistani president Asif Ali Zardari, a Downing Street statement has said a "stable Afghanistan" is in the UK's best interests.
As the Prime Minister has set out previously, a stable Afghanistan is not just in the interests of Afghans, but also in the interests of their neighbours and the UK. We share the same vision for Afghanistan: a secure, stable and democratic country that never again becomes a haven for international terror.
We are working together to achieve it and Afghanistan's neighbours have a vital role to play. It is vital not just for the future security of their citizens, but for their prosperity too.
David Cameron will meet the Afghan and Pakistani presidents tonight in the latest round talks aimed at preventing a Taliban resurgence in Afghanistan when British troops leave next year.
The Prime Minister will dine with Hamid Karzai and Asif Ali Zardari at Chequers as part of his ongoing efforts to help to strengthen Afghanistan-Pakistan relations and promote regional peace and stability.
It comes ahead of in-depth discussions tomorrow focusing on how the Pakistanis and international community can support the Afghan-led peace process.
Foreign ministers, Chiefs of Army Staff, Chiefs of Intelligence and the chairman of the Afghan High Peace Council are expected to attend the third trilateral session since last summer.
David Cameron will meet the presidents of Afghanistan and Pakistan this weekend as part of efforts to prevent a Taliban resurgence when British troops leave.
The Prime Minister will dine with Hamid Karzai and Asif Ali Zardari at his Chequers residence on Sunday, before hosting the first in-depth discussion with them and their top officials on Monday.
It is the third trilateral talks session they have held since the summer. UK officials believe the 2014 deadline for ending combat operations by British and US troops has concentrated minds in Pakistan.
This trilateral process sends a very clear message to the Taliban: now is the time for everyone to participate in a peaceful political process in Afghanistan.
The New York Daily News is reporting the seized Bin Laden documents, set to be published later today, show the al-Qaeda founder was planning to overthrow Afghan president Hamid Karzai and control Afghanistan once the US left the country.
It reports Bin Laden had discussed his plans with the Taliban leadership council, known as the Quetta Shura, and the Haqqani network, which controls the North Waziristan tribal area in Pakistan, with a view of working together to complete the plan.
Afghan President Hamid Karzai has launched a verbal attack on the US, describing his position as at the "the end of the rope" because of the lack of U.S. cooperation after 16 civilians died in an apparent US soldier shooting spree, reports AP.
Karzai met with the families of the victims today and said his delegation sent to investigate the deaths didn't receive the cooperation he'd expected from US officials.
This form of activity, this behavior, cannot be tolerated. It's past, past, past the time.
