The Haqqani network, one of the most notorious terrorist group in Afghanistan, will participate in peace negotiations with the Afghan government and the US if the Taliban want it to, Sirajuddin Haqqani, the network's leader told Reuters news agency on Saturday.
Haqqani said the group had in the past rejected a number of peace overtures because it felt that the US and the Afghan government were attempting to divide various militant factions.
The network no longer has sanctuaries in Pakistan because members feel secure inside Afghanistan, Haqqani said.
The US blamed the network for Tuesday's rocket attacks on the American Embassy in Kabul.
US Defence Secretary Leon Panetta on Thursday said the existence of Haqqani safe havens in Pakistan is unacceptable and vowed he will not let these attacks in Afghanistan continue.
