Many of those injured and killed in a recent Afghanistan suicide bombing were killed by the guards protecting Afghan MPs who fired "deliberately and indiscriminately" into the crowds that included many schoolchildren.
A total of
77 people were killed in the incident. The exact numbers of who killed who are not known. This was one of the worst attacks in Afghan history.
"Regardless of what the exact breakdown of numbers may be, the fact remains that a number of armed men deliberately and indiscriminately fired into a crowd of unarmed civilians that posed no threat to them, causing multiple deaths and injuries," the report said, according to AP.
"It is believed that at least 100 rounds or more were fired into the crowd with a separate group of schoolchildren off to one side of the road bearing the brunt of the onslaught at close range."
Two Afghan government investigations are ongoing.
AP had gotten hold of a UN's weekly security assessment that had the information on it. The United Nations is now saying that the story that AP put out was "premature and is based on incomplete information".
"At the moment, there is real uncertainty," he said in a statement.
"We have to be sure [about the final outcome of the Afghan investigations] before we can make a statement on it.
"We would support giving the authorities time to allow their investigations to run their course."
Mustafa Kazimi was one of those killed in the attack. The MP was a former mujahideen fighter and prominent opposition figure.
The delegation of parliamentarians were visiting a sugar factory in Baghlan province when the suicide bomber denoted himself. His bomb packed full of ball bearings in order to do the most damage.
