An explosion occurred on Friday evening in the Aino area in Paghman district, west of Kabul city, targeting a vehicle in which family members of writer and analyst Assadullah Walwalji were traveling, according to the Kabul police.

Four members of Walwalji’s family, among them his wife and daughter, were killed.

Walwalji was not traveling in the vehicle.

Walwalji’s relatives have accused the Afghan security agencies of failing to provide security to the people.

“Those who are on the leadership level should take responsibility and prove their love to humanity,” said Roay, a resident in Kabul.

“If they (security agencies) fulfill their responsibility, our country will never fall into a  crisis,” said a resident in Kabul, Sirajuddin Hanafi.

“Condemnation and assigning a probe team does not resolve the problems of the Afghan people, I hope that the Afghan government takes such issues seriously and serves justice to the perpetrators who plotted the attack,” said Amir Mohammad Khaksar, a member of parliament.

“Mr. Walwalji’s wife and daughter--who was a student--and his son-in-law and his sister-in-law were there---four people were killed and eight more wounded,” said Abdul Qarloq, a member of the Afghan parliament.

The killing of Walwalji’s family members has also sparked strong retaliation from the public on social media.

“Their (attackers') main target is to create fear and to sabotage the security situation and the system in Afghanistan,” said Mirza Mohammad Yarmand, former deputy minister of interior.

No group has claimed responsibility.

The attack has sparked widespread criticism from Afghans on social media, who blamed the security agencies for their inability to prevent such incidents.

 Walwalji is a popular analyst who frequently speaks on the situation in Afghanistan on local television stations.

The new murder takes place at a time that two influential clerics Mohammad Ayaz Niazi and Azizullah Mofleh were murdered inside the mosques within the span of ten days this month.
