NATO has put off a decision on whether to withdraw all troops from Afghanistan.
Jens Stoltenburg, NATO Secretary General, said there had been "no final decision on the future" of the alliance's presence, after a video conference with defence ministers.
He added that NATO allies will continue to "closely consult and coordinate in the coming weeks".
In December, Mr Stoltenburg said defence ministers could decide in February whether to fully withdraw troops as part of a US-brokered peace deal from 2020.
Under the agreement, a complete NATO troop withdrawal by the end of May 2021 would be possible if the Taliban upheld a number of counter-terrorism conditions.
Earlier this week, Mr Stoltenburg called on the Taliban to reduce violence in Afghanistan after a notable reduction against alliance forces has been marred by a surge in attacks against Afghan forces and civilians.
Britain entered Afghanistan with the US in 2001 and, with troops from both nations still in the country, it has become America's longest war.
There are currently about 750 UK personnel in Afghanistan in a non-combat role as part of a NATO mission.
The number of US personnel in the country is 2,500, the lowest it has been since 2001.
