The Zia government sought help of the Interpol and other foreign agencies to assist in the probe. But Hasina and her associates say there was deliberate delay and misdirection.

Hasina accused the BNP-Jamaat alliance government of masterminding the cross-country bombings on Aug 17, 2005, and said such well-orchestrated attacks would not have been possible without the government's encouragement.

She said that politics of killing and repression in the country had begun during the rule of general Ziaur Rahman and 'whenever his family members come to power, such attacks are mounted on peace-loving and democratic forces'.

Zia and her BNP, which lost last December's election, oppose the government on most issues and allege that the Hasina government was 'selling out to foreign forces'.

BNP secretary general Khandaker Delwar Hossain said his party would boycott the parliament session resuming Sep 7 as the government had 'failed to build a congenial atmosphere'.
