US military suicides on the rise

Suicide rates among US soldiers have reached their highest rate since the beginning of the Afghanistan war, Jim Frederick of Time magazine tells the BBC.

Suicide rates in the US military have reached their highest point since the beginning of the Afghanistan war, with about one death per day.

Those numbers are rising, despite the Pentagon spending $2bn (£1.3bn) per year on mental health.

Time magazine's international editor Jim Frederick spoke to the BBC's Rajesh Mirchandani about what US Defence Secretary Leon Panetta called his "most frustrating challenge".

Mr Frederick said that the most troubling aspect was that "no-one knows why this is happening".
