A suicide blast has killed at least 25 people and left another 60 wounded in eastern Afghanistan, officials say.

The attack on Tuesday afternoon targeted the funeral of a tribal elder in the Durbaba district of eastern Nangarghar province near the border with Pakistan.

Officials said Hamisha Gul, local district governor, injured in the attack, was the likely target.

"The target was the district chief," Sediq Sediqqi, spokesman for the Afghan ministry of interior, told the AFP news agency.

Al Jazeera's Jennifer Glasse reporting from Kabul, said the funeral was of a "prominent village elder" and "the bomber was amongst the mourners".

There was no immediate claim of responsibility.
