Kabul: The son of the Taliban chief was one of the three suicide bombers who died earlier this week while attacking Afghan security checkposts in Helmand province, the terror group's spokesperson confirmed on Saturday.

Abdul Rahman, son of Mullah Haibatullah, was one of the insurgents who carried out three car bomb attacks in Geresk district and launched coordinated attacks on the Afghan forces which prompted the US air support and security reinforcements, reports Efe news.

According to the provincial governor's spokesperson Omar Zwak, between Thursday and Friday, 67 Taliban members were killed and another 80 injured in clashes in the area, where Afghan troops have regained control of three important areas of the district.

Last year, Mullah Haibatullah became the leader of the Taliban, succeeding Mullah Mansur who was killed in a US airstrike in May 2016.
