The death toll from a suicide bomb attack at a protest gathering in the eastern Afghan province of Nangarhar on Tuesday has risen to 68, with 165 wounded, a government official said.
The provincial governor's spokesman, Attaullah Khogyani, issued a statement with a revised casualty total on Wednesday after earlier estimates put the death toll at 32, reports Al Jazeera.
Scores of demonstrators had blocked the highway between the provincial capital Jalalabad and a key border crossing with Pakistan when the bomber struck.
The protesters had come from Achin district to demand the removal of a local police commander.
The attack was one of the worst in Afghanistan for months but security officials have warned that similar attacks are likely if crowds gather for campaign rallies ahead of parliamentary elections in October.
"... the explosion happened and I found myself surrounded by blood and flesh," Zar Khan, one of the injured, told AFP news agency.
