The Afghan Taliban abducted as many as 45 elderly family members of a late Afghan government employee who were attending his funeral, officials said on Tuesday.

The Taliban singled out the old men from a funeral procession carrying the deceased employee's coffin to a graveyard, according to interior ministry spokesman Nasrat Rahimi. The young men in the group were not taken, he said.

The Taliban have consistently warned people not to attend the funerals of anyone working with the Kabul government, according to Payghambarpul Khuram, the head of intelligence in Jawzjan province, where the kidnappings took place.

Khuram disputed the number of people who were kidnapped, saying only six family members were taken and that other local elders were negotiating with the Taliban for their release.

The Taliban did not immediately comment on the abduction.

The insurgent group controls or holds sway over nearly half of Afghanistan, staging near-daily attacks that target Afghan security forces and government officials but also kill scores of civilians.

A suicide car bomb attack on Monday killed at least five Afghan soldiers and wounded four others in the southern Helmand province, ministry of defence spokesman Fawad Aman said.

He said the attacker was shot and killed before reaching his intended target a checkpoint for an Afghan national army compound at which point the vehicle exploded.

The Taliban immediately claimed responsibility for the attack.

United States peace envoy Zalmay Khalilzad on Saturday held the first official talks with Afghan Taliban since President Donald Trump declared a near-certain peace deal with the insurgents dead in September.

The talks will initially focus on getting a Taliban promise to reduce violence, with a permanent cease-fire being the eventual goal, a US statement said. Khalilzad is also trying to lay the groundwork for negotiations between Afghans on both sides of the protracted conflict.
