KABUL, Afghanistan — Taliban insurgents using sophisticated night-vision goggles killed eight Afghan police officers in their beds early Monday near the capital of western Farah Province, Afghan officials said.

The authorities suspect there was also a Taliban infiltrator, according to Naser Mehri, a spokesman for the Farah governor, adding that the only police officer who had survived the attack was being interrogated but had not been charged.

Afghan officials said the killings were the latest in a wave of attacks by the Taliban using night-vision goggles, usually with Russian markings. United States forces introduced night-vision technology in Afghanistan, and American trainers instructed the Afghan Army on how to use them to get an advantage against the Taliban.

Now, the Taliban have apparently managed to obtain the same technology. “Night-vision equipment is used in ambushes by the insurgents and it is very effective,” said Maj. Gen. Dawlat Waziri, the spokesman for the Defense Ministry. “You can see your enemy but they cannot see you coming.”
