The prosecution of August 21 grenade attack cases concluded argument on Monday and sought death penalty for 49 accused, including BNP Senior Vice Chairman Tarique Rahman.
Chief prosecutor of the cases, filed over the grenade attack on an Awami League rally in 2004, Syed Rezaur Rahman concluded the argument at the Speedy Trial Tribunal-1 in Dhaka.
Later tribunal Judge Shahed Nur Uddin set Tuesday for starting the defence argument.
On August 21, 2004, the grisly grenade attack was carried out on an anti-terrorism rally arranged by Awami League at Bangabandhu Avenue during the BNP-Jamaat alliance's rule, aiming to assassinate then leader of the opposition Sheikh Hasina.
At least 24 leaders and activists, including AL's women affairs secretary and late President Zillur Rahman's wife Ivy Rahman, were killed and 300 others injured in the grenade attack.
According to UNB, although Sheikh Hasina luckily escaped unhurt in the attack, her hearing was affected badly.
Later, two cases -- one under the Explosive Substances Act and another for murder -- were filed in connection with the grenade attack.
Besides Tarique Rahman, the cases have 93 other accused, including BNP leader and former Home Minister Lutfozzaman Babar and another leader Abdus Salam Pintu.
