"The incident is a naked attack on the independence and sovereignty of the country," head of the one-member commission Justice Joynul Abedin told reporters.

Commission secretariat officials submitted the 162-page report to the home secretary in the afternoon.

Asked if the government would go public with the report, sources at the home ministry said the ministry would take a decision after reading it.

The commission officials invited journalists by phone Friday evening for an 'informal briefing' on its report prior to the submission yesterday, one and a half months into the grisly grenade attacks apparently to assassinate Leader of the Opposition Sheikh Hasina. However, what Justice Abedin said was merely a speech instead of disclosure of findings.

Journalists repeatedly asked Justice Abedin to disclose the identity and aim of the perpetrators of the attack that killed 20 and wounded over 200, but he said he has limitations making them public.

"I've mentioned in the report whom I've identified and it's up to the government whether it would disclose it and implement (the recommendations made in the report)," he told reporters in his about-half-an-hour speech at the commission's secretariat.

The speech was full of calls for working together to safeguard the country from such an attack, which he termed 'a national catastrophe'.

"The two major political parties should work only for national interests, brushing aside all differences so that the local and foreign enemies cannot create anarchy in the country," he said. "I have called on civil society to share their opinions with leaders of the two major political parties without waste of time and without hesitation."

"They (two major political parties) have to be convinced that only patriotism can pull this country out of the national catastrophe it is in," he added.

Asked to reveal identity of the perpetrators, he said, "I've made hints in my speech."

When pressed for saying if the foreign enemies that he hinted in his speech were behind the attack, he refused to be drawn further on the matter. "All the information is there in my report."

As the journalists told him that the briefing would frustrate the nation that is eagerly waiting to know the identity and motive of the perpetrators, Justice Abedin said, "People know well about the commission's jurisdiction and limitations."

The commission made a detailed report about the security arrangements and neglect by the police and security agencies. It said there is no co-ordination among the agencies, according to sources.

It also made 25/30 recommendations to stop a repeat of such incidents. The recommendations include formation of an elite police force to stop smuggling of arms and explosives through the borders, setting up of a laboratory by the Criminal Investigation Department to quickly examine explosives and evidence after such incidents, a stop to political and religious rallies at undesignated places, and meeting organisers' contacting the police for security.

Justice Abedin suggested the police install several video cameras at some strategic points for filming such public rallies. He recommended that private television channels train up their crew for properly filming such rallies to facilitate identifying the criminals from the footages.

The government formed the commission on August 22 and asked it to submit its report in three weeks. But the commission had the deadline extended for 21 more days.

The commission took statements of 123 people including the injured victims and their doctors, AL leaders and activists present in the rally, explosives experts, journalists and security men.

It sought appointment with Hasina to have her account of the deadly event, but did not have any, as the AL questioned the neutrality of the probe body. The party did not allow it to inspect the sports utility vehicle that carried Hasina to safety immediately after the grenade blasts.

Asked if that hindered the inquiry, Justice Abedin said, "The commission may not have received co-operation from all, which may have somewhat hindered the investigation, but the inquiry is in no way incomplete."
