Militants shot dead four government employees in central Kabul Tuesday in the latest rush-hour violence to rock the Afghan capital.

The city has seen near-daily attacks during the busy morning commute, targeting prominent Afghans including politicians, journalists, activists, judges, and religious scholars.

Kabul police spokesman Ferdaws Faramarz told reporters that gunmen opened fire on a vehicle carrying staff from the Ministry of Rural Rehabilitation and Development, killing four of them.

A separate attack saw a civilian wounded when a bomb targetted another government vehicle, police said.

Tuesday's attacks came a day after three bomb blasts rattled the capital, killing at least one person.

Government negotiators are pushing for a permanent ceasefire, but the insurgents have so far dismissed calls for a truce.

The rise in violence has led US President Joe Biden's administration to launch a review of a deal signed between Washington and Taliban last year that paved the way for the withdrawal of all American troops in coming months.
