(CNN) -- A NATO solider was killed in an insurgent attack in eastern Afghanistan, the International Security Assistance Force said Monday, raising the total number of coalition troops killed in that country this year to 600.
This year was already the deadliest year for coalition and U.S. forces since the battle against the Taliban started some nine years ago.
Last year, 516 coalition troops were killed in Afghanistan. As of Sunday, 600 have died so far in 2010 according to a CNN tally -- with more than two months left in the year.
The morbid milestone comes as the United States is making a strong effort to fight the Taliban. U.S. President Barack Obama ordered the deployment of 30,000 extra U.S. forces to Afghanistan this year, increasing the total American troop commitment to almost 100,000, while at least 25 other countries pledged an additional 7,000 troops.
A new CNN poll shows American support for the war in Afghanistan has never been lower. Only 37 percent of Americans favor the war, and more than half of Americans believe the war has turned into a Vietnam-like quagmire.
Obama's administration has said it would begin taking troops out of Afghanistan around the middle of next year, depending on conditions on the ground.
