"As the government had complicity in the grenade attack, it destroyed all the evidence and didn't help the foreign investigation teams," she alleged.

Hasina made the pungent remarks when the family members of those slain and critically injured in the August 21, 2004 grenade attacks on the Awami League (AL) rally at Bangabandhu Avenue met her at her Sudha Sadan residence.

Twenty-two people, including AL's women affairs secretary Ivy Rahman, were killed and several hundred injured in the attacks.

The AL chief further alleged that thousands of families have been ruined for what she said was BNP-Jamaat coalition government's misuse of power and their greed for money.

She accused the alliance government of patronising Islamist militants and blamed Khaleda Zia for "handing over the national flag to war criminals and Rajakers".

Referring to the latest blasts across the country, the former prime minister again alleged that the government had its hands behind the bombing spree. "Otherwise, it was not possible to conduct such attack," she said.

Hasina shot a question towards the state minister for home affairs as to why he did not take steps when he reportedly had intelligence reports of terrorist attacks.

"The bomb attacks on August 17 were a rehearsal for a future big hit like August 21," she said in her foreboding.

Hasina was critical of the government for having no headache for the victims' families and posed the question: "Shouldn't the government come forward in aid of the victims' families?"

The family members of the victims narrated their sufferings to the opposition leader a day after they commemorated their kin on the first anniversary of the mayhem at the AL rally.
