Afghanistan's Chief Executive, Abdullah Abdullah has accused Pakistan of helping enemies of Afghanistan according to a report in the Afghan media on Tuesday.
"Afghanistan's enemy is Pakistan's enemy. What kind of enemy of Pakistan is this? They kill people here, then move around freely there," said Abdullah.
"Pakistan has not cooperated in anti-terrorism activities over the past 10 months," Abdullah alleged.
"There been no change in the military machinery of the Afghan Taliban over the last 10 months, infact it has gotten stronger," added Abdullah.
The Afghan chief executive also blamed 'double agents' within the Afghan government for the deteriorating security condition in the country.
"The Afghan government should first clear agents within its own structure, because they are more dangerous than insurgents," stated Abdullah.
Abdullah raised the issue of enemy agents within the government and said they were "guiding lights for the enemies of Afghanistan."
Abdullah's comments come a day after Afghan President Ashraf Ghani lambasted Pakistan over a recent wave of insurgent attacks in the capital Kabul that killed at least 56 people.
Since coming to power last year Ghani has courted Pakistan, expending substantial domestic political capital in the process, in hopes Islamabad will persuade the Taliban to come to the negotiating table.
But his comments on Monday are the strongest yet against Pakistan.
A statement by the Foreign Office released on Monday said: "We have taken note of the press conference by the President of Afghanistan held in Kabul today and its contents relating to Pakistan.
The statement said Pakistan was itself the biggest victim of terrorism, with human losses exceeding 60,000.
The FO statement said Prime Minister Nawaz Sharif during his visit to Kabul in May said Pakistan considered enemies of Afghanistan as its own enemies, and has been extending complete cooperation to Afghanistan in combating terrorism.
Pakistan remains committed to supporting and facilitating an Afghan-led and Afghan-owned peace and reconciliation process in Afghanistan, added the FO statement.
