Prime Minister Jan Peter Balkenende said Sunday Dutch troops will begin leaving southern Afghanistan in August, since his caretaker government has no authority to accept a NATO request to stay on. Speaking a day after his coalition government collapsed over the issue, Balkenende said the Netherlands will end its role in Uruzgan province, where 21 Dutch soldiers have been killed since the mission was first deployed in 2006, AP reported. «Our task as the lead nation ends in August this year,» he said on Dutch television. A marathon cabinet meeting that broke up before dawn Saturday ended with the walkout of the second largest party in the government, Labor, which accused the dominant Christian Democratic Alliance of reneging on a 2007 agreement to bring the troops home this year.
