NYT: At Least 23 Soldiers Killed in Insider Attack in Afghanistan

At least 23 [ANA] soldiers were killed while they were sleeping on Saturday in an insider attack in eastern Afghanistan, officials said, the latest episode of enemy infiltration that has raised concerns about a new local military force billed as the hope for holding territory recaptured from the Taliban.

The Taliban infiltrator, who was on duty at a military base in Ghazni Province, opened fire on his colleagues, wiping out almost the whole unit, officials said. The attacker then seized all weapons and equipment in the base and joined the insurgency.
