Al Jazeera has learned of a face-to-face meeting between Hamid Karzai, the Afghan president, and a man who once tried to kill him.

That man is the leader of the Haqqani network, described by the United States as one of the three main insurgent groups, alongside the Taliban and Al Qaeda.

Sirajuddin Haqqani, who's group is based across the border, is said to have been accompanied by Pakistan's army chief and the head of its intelligence services.
