US military death toll in Afghanistan reaches 2,000

The US military has suffered its 2,000th death in the Afghan war - with a suspected "insider" attack at a checkpoint.

A US soldier and a foreign contractor were killed in the east of the country, apparently by a rogue member of the Afghan security forces, BBC reports.

"Insider" attacks sharply increased this year, prompting the coalition to suspend joint operations this month.

However, such operations resumed in recent days, the Pentagon said.

The nationality of the contractor was not given immediately.

The American death toll goes back to the US-led invasion of Afghanistan in 2001.
