Three U.S. troops wounded after Afghan soldier 'mistakenly' opens fire

An Afghan soldier 'mistakenly' opened fire on Sunday inside a base in Afghanistan's southern Helmand province, wounding three U.S. soldiers before being shot dead, an Afghan official said.

Colonel Mohammad Rasoul Zazai, an army spokesman, said the soldier had made a "mistake" and had not fired deliberately, reports the Guardian.

A coalition-run Twitter account said an Afghan soldier shot and wounded three American soldiers, without providing further details.

Most foreign combat troops withdrew from Afghanistan at the end of 2014, 13 years after they ousted the Taliban from power, but about 13,000 NATO-led soldiers remain to help advice and train Afghan forces fighting a revived Taliban insurgency.
