Afghan officials say a suicide bombing has rocked Kabul close to the area where scores of people had been protesting against what they called the government's failure to protect the country’s mainly Shi'ite Hazara minority from Taliban attacks.
Security officials told FRE/RL that a suicide bomber detonated his suicide vest on November 12 before he was able to reach the protesters.
There was no immediate news on casualties.
Hundreds of people had marched through the night from the western parts of Kabul to the Presidential Palace, in the city center, to protest against the lack of security in districts in Ghazni and Oruzgan provinces that are inhabited mainly by ethnic Hazara.
The districts have been under Taliban attacks for almost one week.
The total number of casualties was not clear, but officials earlier said that the militants killed 15 civilians and 10 members of the special forces in Ghazni Province on November 11.
In the western province of Farah, at least 37 members of the Afghan security forces were killed in attacks late on November 11 by Taliban fighters on checkpoints that triggered hours of fighting, according to local officials.
