President Trump plans to announce the drawdown of some 4,000 troops from Afghanistan as early as next week, official sources told NBC News.

The US has between 12,000 and 13,000 troops in Afghanistan now. It was unclear when the troop withdrawal would begin.

Talks between US peace negotiators and the Taliban, which controls nearly half of the country, resumed last week after breaking down in September.

The drawdown would be a combination of some troops redeploying elsewhere early and others not being replaced when they rotate out, according to officials.
