Afghan President Hamid Karzai has suspended talks with the US on a security pact, accusing Washington of providing "inconsistent statements" on peace talks with the Taliban.
"In a special meeting chaired by President Hamid Karzai, the president has decided to suspend talks about a security pact with the US because of their inconsistent statements and actions in regard to the peace process", Karzai's spokesman Aimal Faizi told Reuters.
The US Embassy in Kabul said it was preparing a statement following the announcement.
Afghan President Hamid Karzai will travel to Qatar to discuss peace negotiations with the Taliban, the Afghan Foreign Ministry said today.
Karzai's trip, which is set to take place over the next few days, will be the first time an Afghan president has held peace talks with the Taliban in the sovereign Arab state.
The leader will also address the opening of a Taliban office in Qatar, which he has agreed to on the condition the Taliban ends its links with Al-Qaeda.
Karzai's trip comes after fractures in his relationship with Washington. He recently blasted US Defense Secretary Chuck Hagel for holding talks with the Taliban in Qatar without him and accused the US of reneging on a deal to release Afghan prisoners from a US detention centre in Bagram.
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.
