The United Nations has condemned alleged abuses by American forces in Afghanistan, calling them "totally unacceptable".

Asked about a report that U.S. troops allegedly burned the bodies of two Taleban fighters to taunt other fighters, a U.N. spokesman said such abuses are an affront to the work of the international community in Afghanistan. 

The United Nations issued a similar statement in May amid claims of abuses of Afghan prisoners by U.S. forces.

Afghan President Hamid Karzai has also condemned the purported burning incident and ordered an inquiry.

U.S. Defense Secretary Donald Rumsfeld said the alleged actions do not represent the overwhelmingly positive behavior of the U.S. military, adding he wants the U.S. military in Afghanistan to accelerate its own investigation.
