The TOLOnews broadcaster reported that the suicide attack, carried out in Kabul's Taimani district on Sunday afternoon, targeted the supporters of Ahmad Shah Massoud, the country's deceased political leader fighting against the Taliban insurgency, who were commemorating his death anniversary.
Kabul police chief spokesman Hashmat Stanekzai said that the attacker was also driving a motorcycle.
According to the news outlet, Afghan National Directorate of Security officers have eliminated another suicide attacker earlier in the day, who had been planning to carry out a blast, targeted against Massoud supporters, near the US Embassy in Kabul.
Massoud, Afghan political and military leader, was assassinated in a bomb attack on September 9, 2001, after having survived several other assassination attempts. Due to his contribution to the fight against the Taliban movement, Massoud was awarded the rank of Afghanistan's National Hero.
