It was the first confirmed report of deadly Taliban infighting after an announcement last month that Mullah Omar had been dead for more than two years.
Rafiq Sherzai, spokesman for the Herat Regional Hospital, said on Tuesday that 18 people were also wounded in the blast late Monday.
The attack Saturday struck near the private Shinozada hospital in Kabul’s Macrorayan neighborhood. No group immediately claimed responsibility for the attack.
Sultan Faizy, who is Dostum’s spokesman, says the ambush happened on Friday afternoon in northern Faryab province as the convoy was driving through Qaysar district.
Hassib Sediqi, the spokesman for the National Directorate of Security, said today that Afghan authorities have confirmed “Pakistani military interference” in the attacks last Friday.
“We know they have sanctuaries there, we know they are active there,” Ghani said, referring to Taliban leaders living in Pakistan. “We need all those activities to be stopped.”
This attack comes days after series of suicide attacks in the Afghan capital killed dozens and wounded hundreds more.
The statement is a sharp attack on Mullah Akhtar Muhammad Mansur, who was controversially picked to replace Mullah Omar after the organisation announced the jihadist leaders’ death last month.
Two blasts, one near a government and military complex in a residential area and the other a suicide bombing outside a police academy, killed at least 35 people.
The military helicopter went down due to technical reasons in Shinkay, a district relatively free of insurgent activity in Zabul.
Din Mohammad Darwish, spokesman for the governor of Logar province, near Kabul, says the dead from Thursday’s attack include three police officers and five civilians. Five police are among the wounded.
The move assumes significance in the wake of heightened security threat to Indian missions in Afghanistan, following a leadership change in Taliban after Mullah Omar’s death.
Fledgling peace talks between the Taliban and the government halted last week when officials announced Taliban figurehead Mullah Mohammad Omar had died in April 2013.
Nangarhar has seen heavy fighting in recent months between militants purported to be from the Taliban and the Islamic State group, battling for control of trade routes.
Citing Afghan government and intelligence sources, the BBC said that Mullah Omar died two to three years ago. No further details were released.
