Taliban ambush kills 22 Afghan police officers
The attack took place in Farah province on Sunday with at least two officers from the police patrol also injured, said Shir Ahmad Weda, director of the public hospital in the provincial capital.
The Taliban claimed responsibility for the attack in a WhatsApp message, saying 25 police were killed and four wounded.
"Four vehicles were destroyed and a large quantity of weapons were seized," Qari Yousuf Ahmadi, a spokesman for the militants, added.
On Sunday, hundreds clashed with police during the protest. Three policemen were shot and wounded and another 20 were hit by stones thrown by the protesters, who torched two police checkpoints.
"I can hear sporadic sound of shooting form the area," said lawmaker Nasrullah Sadeqizada of Monday's protest.
The US is also pushing for a peace deal with the Taliban, before presidential elections next April.
The Taliban view the US-backed government in Kabul as a dysfunctional Western puppet and have refused repeated offers to negotiate with it.
