Iranian Parliament Speaker Ali Larijani condemned the US forces for massacring the civilian people in Afghanistan, and said the Afghan people will never forget the crime. The savage act of the US soldiers in massacring rural people in Afghanistan is not an event to be easily forgotten, Larijani said, addressing his colleagues at the parliament on Tuesday. He also referred to the crimes committed in Afghanistan and Palestine in the past few days, and said the US and the Zionist regime were behind those crimes. He said the crimes are conducted in such brutal manners that deprive Muslims and all human beings in general from any sense of security. An American sergeant killed 16 civilian Afghan people: nine children, three women and four men in two villages near his combat outpost in Southern Afghanistan on Sunday. Leaders from across Afghanistan\'s fragmented political terrain have expressed anger and outrage over the attack in the district of Panjwai, in Kandahar province Afghan President Hamid Karzai condemned the weekend bloodshed as \"unforgivable.\" Afghanistan\'s parliament demanded a public trial for the suspect, and the Afghan Taliban described US troops as \"sick-minded American savages\" and vowed to exact revenge. In a fresh statement Tuesday, the Taliban also said it would take revenge \"by killing and beheading Americans anywhere in the country.\" There are fears that Sunday\'s killings could reignite the anger that led to deadly riots directed at international forces last month over the burning of Qurans by US troops. That was one of a string of incidents involving American forces that have strained ties between the United States and Afghanistan.
