KABUL- A Taliban-suicide car bomber struck a NATO convoy in the Afghan capital Tuesday, killing six troops, five of them American, officials said. Twelve Afghan civilians also died ��" many of them on a public bus in rush-hour traffic. The powerful blast occurred on a major Kabul thoroughfare that runs by the ruins of a one-time royal palace and government ministries. It wrecked nearly 20 vehicles, including five SUVs in the NATO convoy, and scattered debris and body parts across the wide boulevard. The body of woman in a burqa was smashed against the window of the bus. The attack ��" the deadliest for NATO troops in the capital since September ��" comes despite a ramped up effort by Afghan authorities to intercept would-be attackers and better secure a capital city that saw a spate of brazen attacks this winter. In the last such attack in February, suicide bombers stormed two small downtown hotels and killed 16 people. Taliban spokesman Zabiullah Mujahid told The Associated Press in a phone call from an undisclosed location that the bomber was a man from Kabul and his car was packed with 1,650 pounds (750 kilograms) of explosives. The target of the attack was the foreign convoy, he said. U.S. troops and Afghan police held a security cordon around wrecked vehicles at the blast site in the west of the city. Emergency workers zipped the dead into body bags and lifted the injured into ambulances. "I saw one person laying on the ground with no head," said Mirza Mohammad, who was on his way to work when the blast happened up the road. Police officer Wahidullah, who goes by one name, said he saw the body of woman in a burqa smashed up against the window of the bus. "Everywhere was dead bodies," Wahidullah said. At least 12 Afghan civilians died and 47 were wounded ��" most of them in the bus, the Interior Ministry said. NATO said six of its service members were killed in the attack, and U.S. forces spokesman Col. Wayne Shanks confirmed that five of those were American. The nationality of the sixth was not immediately disclosed. It was the deadliest attack for NATO in the capital since a September suicide bombing that killed six Italian soldiers. The attack comes as NATO readies a major offensive in the southern province of Kandahar, a major Taliban stronghold. NATO Secretary-General Anders Fogh Rasmussen condemned the attack and said it would not deter NATO's efforts in Afghanistan. "NATO remains committed to its mission to protect the Afghan people and to strengthen Afghanistan's ability to resist terrorism," Rasmussen said in Brussels. "There were casualties among the NATO forces as well as among civilians ��" women, children and schoolchildren," Karzai told a news conference. NATO said that five of its vehicles were damaged as well as more than a dozen civilian vehicles. There were no obvious military vehicles among the wreckage, but NATO troops often travel in unmarked SUVs in the capital. The Feb. 26 attack against two residential hotels in the capital killed six Indians, along with 10 Afghans. Afghan authorities blamed the attack on Lashkar-e-Taiba, the same Pakistan-based Islamist militia that India blames for the 2008 Mumbai terrorist attacks that killed 166 people. ___
