Afghan President Hamid Karzai (C) shakes hands with an unidentified man as he is welcomed by German Foreign Minister Guido Westerwelle (R) upon his arrival on December 2, 2011 at the Koeln/Bonn military airport, in Cologne, western Germany, ahead of a major international conference on Afghanistan.

Hamid Karzai has accused Pakistan of sabotaging peace talks with the Taliban by refusing to take part in an international conference on Afghanistan's future in Bonn.
"Up until now, they have sadly refused to back efforts for negotiations with the Taliban," Agence France-Presse reported the Afghan president as telling Der Spiegel.
Karzai's comments were reported in German and due to be published on Monday, according to AFP.
The Bonn meeting, Der Spiegel wrote, was "supposed to convince Kabul that the West will not abandon it after foreign troops leave in 2014."
The conference comes 10 years after a previous landmark meeting on Afghanistan in the German city.
