Munawar Hassan, Jamaat-e-Islami chief, described that the execution of Molla was a "deplorable" act. In a statement, Hassan said Molla had an "unflinching spirit" which was commendable. He also added that his execution was nothing but a mockery of justice.
The Pakistan Jamaat leader slammed Islamabad for being silent on the execution
Hassan added that the Pakistani government could have convinced its Bangladeshi counerpart by referring to the agreement between former Pakistan prime minister Zulfiqar Ali Bhutto and Bangladeshi leader Sheikh Mujibar Rehman.
Jamaat will also hold in-absentia funeral prayers for Jmolla in various cities across Pakistan on Friday.
Jamaat also criticised the Pakistani government for not speaking up against Molla's execution.
Molla, 65, became the first person to be executed for the massacres during the liberation war of 1971.
The execution is also expected to lead to conflict between political forces in Bangladesh. Supporters of the ruling Awami League celebrated the execution of Molla while the Jamaat called a nationwide strike on Sunday to protest against the act.
