and Vice-President Hashimi's comments in the OP are right in line with similar comments from the Prime Minister's Office (read story below).
The question is why is the US trying so hard to deny that civilians were massacred in Ishaqi. One possible answer could lie in the Haditha massacre by Marines. The Bush regime has already portrayed what happened in Haditha as an aberration by over-stressed troops. Any admission that Haditha is but the tip of the war crimes iceberg, would undercut Bush's Long War and increase demands for a total troop withdrawal from Iraq.
Iraqi PM: U.S. rushed Ishaqi probe
Said 'questions and doubts' still hover over civilian killings
Saturday, June 3, 2006 Posted: 1914 GMT (0314 HKT) BAGHDAD, Iraq (CNN) -- The U.S. military rushed to judgment in its exoneration of U.S. troops involved in the March 15 raid that killed civilians in Ishaqi, said an aide to Iraq's prime minister on Saturday.
There are too many "questions and doubts" surrounding the raid 60 miles north of Baghdad, said Adnan al-Kadhimi.
"The Iraqi government should continue its own investigation until the truth can be found," he said.

Maj. Gen. William B. Caldwell IV, the Multi-National Force-Iraq spokesman, conceded that as many as "nine collateral deaths" may have occurred in Ishaqi, but that investigators could not determine the exact number "due to the collapsed walls and heavy debris."
Nonetheless, a government committee made up of several Iraqi ministries is investigating, and if it finds wrongdoing, it wants an apology, as well as compensation, al-Kadhimi said.
