The Haqqani terrorist network was accused of the deadly suicide attack in Eastern Paktika province which left at least 57 people dead.
The Afghan Intelligence – National Directorate of Security (NDS) said the Haqqani Network was behind the suicide attack, Khaama Press reported.
According to local government officials, at least 57 people were killed and around 60 others were injured in the suicide attack which took place around 4:30 pm local time.
The suicide bomber detonated his explosives during a volleyball match in Yahya Khel district which was attended by hundreds of spectators.
No group including the Taliban militants has so far claimed responsibility for the attack.
The Haqqani terrorist network is accused of staging numerous cross-border attacks from their base in North Waziristan, including the 19-hour siege at the US Embassy in Kabul in September 2011.
Haqqani network was formed in the late 1970s by Jalaluddin Haqqani. The group is allied with Al-Qaeda and the Afghan Taliban and cooperates with other terrorist organizations in the region.
The network is considered the most lethal insurgent group targeting International Security Assistance Force (ISAF) and Afghan personnel in Afghanistan.
