Two people have been detained after gunmen opened fire on a wedding in the Afghan province of Nangarhar, a Taliban spokesman said.
Afghan broadcaster TOLO News said that at least two people were killed and 10 injured after the men opened fire on the wedding party on Friday.
The men were thought to have been local forces belonging to a nearby checkpoint, according to a family member at the wedding.
Noor Hazrat, a family member of the victims, said to the broadcaster: "I told them that they are young - let them play the music - but they dragged me back and opened fire, some of the boys were wounded and two others were killed."
Another witness, Abdul Bassir, was quoted as saying: "It was nearly midnight.
"Three people entered the house.
"One of them broke the musical instruments and then went out and then opened fire on approximately 50 people."
A Taliban spokesman said that the gunmen did not belong to them and that the incident was caused by a personal dispute.
Zabihullah Mujahid told news agency AFP: "Last night, at the wedding of Haji Malang Jan in Shamspur Mar Ghundi village of Nangarhar, three people who introduced themselves as Taliban entered the proceedings and [asked] that the music stop playing.
"As a result of firing, at least three people have been killed and several others have been injured.
"Two suspects have been taken into custody by the Taliban in connection with the incident and one who escaped is still being pursued.
"The perpetrators of the incident caught, who have used the name of the Islamic Emirate to carry out their personal feud, have been handed over to face Sharia law."
