The killing of Kibria in a grenade attack is well-connected with the killing of Bangabandhu and his family members on 15th August 1975, the jail killing on 3rd November 1975, and the grenade attack on an Awami League rally on 21st August 2004 and other similar attacks in recent times as part of an elimination design, they said.

Senior Awami League leaders including Zillur Rahman, Suranjit Sengupta, Abdul Motin Khosru, Dr Mohiuddin Khan Alamgir, poet Syed Shamsul Haq and advocate Tarana Halim among others took part in the memorial discussion.

The meeting also registered protest against the killings one after another in grenade and bomb attacks.

"Although Kibria was a sitting lawmaker, there was not a single police personnel at his meeting venue in Habiganj," said Abdul Motin Khosru, adding that it was "a designed killing in connivance with the government."

The spree of grenade attacks began since the biggest ever Chittagong arms haul with which frontline leaders of ruling BNP were found involved, Khosru said.

"The killers of Bangabandhu and Kibria are interlinked by the same ideals," said Suranjit Sengupta, "So, it is futile to demand justice from the ruling coalition."

All the incidents since 1975 are interlinked in a well-designed blueprint against Awami League, said Zillur Rahman, whose wife Ivy Rahman was killed in the August 21 grenade attack last year.

"These incidents should not be considered in isolation," said poet Syed Shamsul Haq.

Jote activist advocate Tarana Halim, who spoke as one of Kibria's family members, said that if the killers of Kibria go unpunished, "none of us will remain safe in the society."

As to sending helicopter to bring Kibria from the spot of grenade attack, she said that the government claim is a blatant lie.

Film director Alamgir Kumkum, actor ATM Shamsuzzaman and Kibria's daughter-in-law Rina Sultana Kibria also spoke.
