President Mamnoon said Pakistan wanted a peaceful and stable Afghanistan.

His comments came after Afghanistan's National Security Council, which is chaired by President Hamid Karzai, said "without doubt foreign intelligence services beyond the border" were behind Friday's suicide attack on a Kabul restaurant that killed 21 people.

Speaking at the launch of a new book about Afghanistan by a Pakistani think-tank, Hussain insisted his country's support for the fight against extremism was in earnest.

"Sometimes, our commitment is questioned. The reality is that, leaving aside Afghanistan, there is no other country in the world than Pakistan that has paid a higher price," Hussain said, according to a statement released by his office.

"Pakistan stands for a peaceful, stable, united and prosperous Afghanistan. We have consistently maintained that the solution of Afghanistan lies within Afghanistan."
