Nato's top commander in Afghanistan has said increased troop levels could bring a negotiated peace with the Taliban. US Gen Stanley McChrystal told the UK's Financial Times newspaper that there had been "enough fighting". He said a political solution in all conflicts was "inevitable". His remarks came as the top UN envoy in Kabul said it was time to talk to the militants.
The former leader of the Soviet Union, Mikhail Gorbachev, has warned Nato that victory in Afghanistan is impossible. Mr Gorbachev said that the US had no alternative but to withdraw its forces if it wanted to avoid another Vietnam.
