September 18, 2009 - A U.S. service member and a Canadian soldier died in separate roadside bomb explosions in southern Afghanistan, officials said Friday, announcing new deaths from a day that claimed the lives of a total of nine international troops.

The American and Canadian died Thursday, the same day a car bomber killed six Italian troops in a brazen attack in the heavily guarded capital of Kabul. A NATO soldier also died Thursday of wounds from an earlier attack.

The car bomb in Kabul killed 10 Afghan civilians as well as the Italians, leaving a crater 3 feet (one meter) deep and nearly twice as wide. Italian Premier Silvio Berlusconi called Friday for a "transition strategy" to allow the Afghan government to do more for its own security - and decrease the number of international troops in Afghanistan.

The Italian deaths were the country's greatest single loss in the war, but Berlusconi said his government remained committed to defending democracy in Afghanistan, "which is still very far from being a modern and civilized country."

At the bomb site in Kabul on Friday, Afghan men in traditional tunics peered into the blackened pit in the road - a major thoroughfare connecting the airport to the capital - and mourned the deaths of neighbors and relatives.

Ghulam Sakhi said the two storekeepers on each side of his carpentry workshop were among those killed in the fourth major attack in the capital in five weeks.

The resurgent Taliban has increased attacks sharply this year - the deadliest yet for the international forces in Afghanistan. The Islamist extremists run a shadow government in the south and their attacks have increased ahead of last month's presidential election and with the arrival of 21,000 more American troops.

U.S. military spokeswoman Capt. Elizabeth Mathias said the American died when his patrol struck a bomb planted in the road. She did not provide his name.

Canadian Brig. Gen. Jonathan Vance said Pvt. Jonathan Couturier, 23, was killed as he returned from a mission to root out Taliban weapons caches in the southern province of Kandahar.

Bombs planted in and around roads are one of the main weapons used by the insurgents, now accounting for the majority of U.S. and NATO casualties.

This year has been the deadliest for American and NATO troops since the 2001 invasion to oust the Taliban for sheltering al-Qaida leaders who plotted the Sept. 11 terrorist attacks in the U.S. Violence has been particularly harsh in the south, where thousands of U.S. troops have deployed to bolster the Canadian and British-led operations in the Taliban heartland.

The U.S. and NATO have a record number of troops in Afghanistan - nearly 100,000 in total - and the top commander in Afghanistan, Gen. Stanley McChrystal, is likely to soon request thousands more.
