NATO's supreme commander, US General John Craddock, holding talks in Afghanistan on Tuesday with officials and troops involved in an intensifying fight against insurgents, officials said. Craddock, who heads NATO's military forces, was due to meet Afghan Defence Minister Abdul Rahim Wardak on Wednesday, the defence ministry said. He would also meet NATO troops in theatre, an International Security Assistance Force (ISAF) official told a foreign news agency without being able to give details. Craddock's visit comes days after he caused controversy by reportedly suggesting that NATO soldiers should be allowed to kill drug traffickers even without proof of ties to insurgents who are in part funded by the opium trade.
