Afghanistan cannot be ‘a laboratory of terror,’ US President Donald Trump said amid a discussion about the possible withdrawal of US troops from Afghanistan,

"Look we're there for one reason, we don't want that to be a laboratory ... It can't be a laboratory for terror. And we've stopped that we have a very, very good view," CNN reported quoting the president.

"We're looking at Afghanistan. We're talking to Afghanistan, both the government and also talking to the Taliban, having very good discussions. We'll see what happens ... We'll decide whether or not we'll be staying longer or not," he added.

The peace plan is expected to formally formalize a significant withdrawal of US troops from Afghanistan - from about 15,000 troops - and formalize the Taliban’s official counter-terrorism commitments in Afghanistan.

The Taliban do not recognize the Afghan government, which does not participate in the talks that the US is conducting with the Taliban in Qatar.
