At least 21 suicide bomber were involved behind the coordinated suicide attacks on provincial National Directorate of Security (NDS) compound, Afghan National Police (ANP) Quick Reaction Forces headquarter and provincial Information and Culture Directorate.
The attack was launched after two of the suicide bombers detonated the vehicle-borne improvised explosive device (VBIED) near the entrance gate of NDS and Quick Reaction Forces compounds.
NDS officials said Saturday that six of the suicide bombers were from Pakistan who were trained and deployed to Ghazni for the attack.
Haseeb Sediqi, spokesman for the National Directorate of Security (NDS) said it took 45 days for the Quetta Council to plan the coordinated attack in Ghazni province.
Seiqi further added that the suicide bombers were trained in Quetta city of Pakistan before they were deployed to Ghazni.
The Taliban militants group in Afghanistan claimed responsibility behind the coordinated attack.
