Taliban ambush attack kills 22 police personnel
The attack on the police convoy in Farah province follows a wave of violence across Afghanistan in recent weeks, including a suicide bombing inside an army base mosque on Friday, and intensifying efforts to convince the Taliban to end the 17-year war.
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 number of weapons were seized," Qari Yousuf Ahmadi, a spokesman for the militants, added.
Provincial police spokesman Mohibullah Mohib said the convoy had been travelling from Farah city to Juwain district when it came under attack.
Mohib put the death toll at five with another seven wounded.
At least 27 soldiers were killed in Friday's suicide attack in a mosque on an army base in the eastern province of Khost.
IS claimed responsibility for the explosion, which also wounded at least 79 service members.
That came days after a suicide assault on a religious gathering in Kabul that killed at least 55 people and wounded 94.
Since the start of 2015, when local forces took over from US-led NATO combat troops to secure the country, nearly 30,000 Afghan soldiers and police have been killed, President Ghani revealed this month -- a figure far higher than anything previously acknowledged.
Experts have warned the attrition rate is unsustainable.
His comments underscore an apparent increasing sense of urgency in the White House and among American diplomats for such a deal to be done quickly.
But Afghan election organisers said Monday they were considering delaying the poll for three months amid fears the ballot could derail efforts to persuade the Taliban to talk.
