One prostester was killed and five others wounded during a clash with security forces in downtown Kabul in the early hours of Tuesday morning.
According to one of the protest organizers, Ramish Noori, the clash was sparked when security forces tried to dismantle their tents in Shar-e-Now early Tuesday.
He said the clash started at about midnight and lasted until about 4am.
Protesters have been holding a sit-in demonstration in the city since early this month after protesting against the lack of security in the country following the May 31 truck bombing in Kabul that killed over 150 people.
Two days after the truck bombing, the protesters held a mass rally through the streets of the capital. However police opened fire on them, killing at least five.
