NATO has confirmed that six American troops died in a Sunday roadside bombing in Afghanistan. The Taliban has claimed responsibility for the attack.
The soldiers reportedly died when their tank ran over a bomb in Wardak province, south of Kabul.
To date, more than 225 NATO service members have lost their lives in Afghanistan.
Meanwhile, in a separate act of violence, a married Afghan woman was publicly executed for allegedly running off with another man.
President Hamid Karzai, along with U.S. Embassy in Kabul and the top commander of U.S. and NATO forces, condemned the killing.
"Such a crime is unforgivable in the sacred religion of Islam and the laws of the country," Karzai said.
"Let's be clear, this wasn't justice, this was murder, and an atrocity of unspeakable cruelty," American Gen John Allen, commander of International Security Assistance Force in Afghanistan, said in a statement.
"The Taliban's continued brutality toward innocent civilians, particularly women, must be condemned in the strongest terms," he said.
