Ten people were killed Wednesday as a suicide bomber blew himself up at a gathering of tribal elders in eastern Afghanistan's Kunar province, interior ministry spokesman Zemarai Bashary said.

"A suicide attacker targeted a gathering of tribal elders in the Asmar district of Kunar today," Said Bashary.

"Ten people have been martyred and seven others have been injured."

He said the dead included a key pro-government elder in the area.
