A senior figure in the Taliban-allied Haqqani network was gunned down on the outskirts of Islamabad, a Pakistani police source told Efe on Monday.
The incident took place Sunday night when two unknown gunmen riding a motorcycle opened fire on Nasiruddin Haqqanu, the son of network founder Jalaluddin Haqqani, the police officer said.
A member of the Pakistani Taliban close to the Haqqani network confirmed the death of Nasiruddin to Express Tribune.
That source added that the body had been taken to the North Waziristan tribal zone for burial.
A year ago, the United States included the Haqqani network, the organization responsible for some of the bloodiest attacks on allied troops in Afghanistan, on its list of terrorist organizations.
The presence of numerous leaders of the group on Pakistani soil, especially in North Waziristan, has been a regular point of friction between Islamabad and Washington, which has demanded that Pakistani authorities take more decisive action against them.
The Haqqani faction, which is linked with the Afghan Taliban but maintains a certain autonomy, controls broad zones of southeastern Afghanistan via a strategy of tribal and ideological vassalage.
Nasiruddin's brother, Sirajuddin Haqqani, is considered by many security analysts to be the leader of the network, which has thousands of members.
According to various intelligence reports cited by the media, Nasiruddin was the son of the network's founder and an Arab wife, and his fluent Arabic allowed him to act as the regular liaison between his group and other jihadist entities such as Al Qaeda.
A third brother of the clan, Badruddin, died in August 2012 in a U.S. drone strike in the Pakistani tribal zones. EFE
