On 31 October 2016, the ceasefire with Farc rebels will end, Colombian President Juan Manuel Santos has said.
All sides in Colombia want an end to more than 50 years of fighting.
However opponents of the government insist on a renegotiation.
Negotiators have resumed talks in Cuba to try to restart a peace deal following its rejection in Sunday’s referendum.
“I hope we can move forward to realise the necessary agreement to find a solution to this conflict,” Mr Santos said in a televised address.
