Colombia’s government and FARC guerrillas will sign a new peace accord in Bogota Thursday, after a previous agreement to end the country’s half-century of conflict was rejected in a referendum, both parties said.

The new accord will be submitted to Congress for approval, rather than put to another referendum.

Last month voters taking part in that referendum surprisingly rejected the first accord. Critics said it went too easy on the rebels, who have been waging what is now Latin America’s last insurgency.

“The government and FARC delegations have agreed to sign the final agreement to end the conflict and build a stable and lasting peace,” negotiators from both sides said in a statement Tuesday.

The new accord was first announced on November 12.

The signing will take place at 11:00 am (1600 GMT) at the Colon Theater in Bogota, they said.

The accord will then be submitted to Congress, the two sides said.

“We are working out the procedures necessary for this,” they said.
