A teenage suicide bomber blew himself up at a wedding in Afghanistan on Friday, killing six people and injuring 20 others, an official said.
The attack took place at the residence of a tribal elder in Pachir-Aw-Agam district of Nangarhar province, an official told Efe news.
The elder, also the commander of a pro-government militant group, was among the dead, the official added.
No group has claimed responsibility for the attack.
A Taliban spokesperson denied the insurgent group's involvement.
"The blast at a wedding party in Nangarhar has nothing to do with the mujahideen of the Islamic emirate," Zabihullah Mujahid tweeted.
