On March 15th, 2006, in Ishaqi, which is a town about 100km (60 miles) north of Baghdad, a number of Iraqi's died. The U.S. military claimed these Iraqis were involved in a firefight after a tip-off to the effect that an al-Qaeda supporter was visiting a house in the town. According to military authorities, the building collapsed under heavy fire, killing four people - a suspect, two women and a child.
However, the BBC has uncovered a video-tape that shows a number of dead adults and children at the site with what our world affairs editor John Simpson says were clearly gunshot wounds. In the days after the "firefight", Iraqi police made the claim that US troops had deliberately shot up to 11 people.
I guess we'll see where this goes. The tape was obtained from "a hardline Sunni group opposed to coalition forces". However, it has been cross-checked against other images and is "believed" to be genuine.
