US Defense Secretary in Afghanistan VOA News 02 September 2010 U.S. Defense Secretary Robert Gates is in Afghanistan for meetings with President Hamid Karzai and the commander of NATO forces in the country, U.S. General David Petraeus. Gates arrived in Kabul Thursday from Baghdad, where he attended ceremonies Wednesday marking the end of the U.S. military's seven-year combat mission in Iraq. U.S. President Barack Obama said Tuesday the drawdown of U.S. forces in Iraq has freed up resources to go on the offense against insurgents trying to topple the Karzai government. Mr. Obama said he will start a transition to Afghan security responsibility next August. But, he added the pace of U.S. troop reductions in Afghanistan will be determined by "conditions on the ground." NATO says the latest fighting in Afghanistan has killed two American soldiers and a Taliban commander. The alliance says the U.S. soldiers were killed Thursday in separate attacks in eastern and southern Afghanistan, regions where Taliban militants are strongest. This week has been deadly for U.S. troops with a spate of militant attacks, killing at least 21 since Saturday. NATO said it killed the Taliban commander in an air strike Wednesday as he rode his motorcycle in the eastern province of Paktika. Officials said the commander led a group of insurgents involved in laying roadside bombs and smuggling foreign fighters into Afghanistan. In August, Taliban militants killed 80 international troops, 56 of them Americans, while NATO said combined forces killed 160 militants and detained more than 500 others.
