The head of the U.N. political mission in Colombia says Colombians would like to see quick agreement on a new peace deal to replace the one rejected by voters.

Jean Arnault said the protocol agreed to by the government and Colombia's largest rebel movement on Oct. 13 in Havana following the defeat is a very serious commitment on the separation of forces, "and I would even say to some extent amounts to the end of the conflict."

He said Wednesday that there is a very strong consensus in the country that "there cannot be a return to war."

Colombian President Juan Manuel Santos is engaged in three-way talks with the FARC rebels and the opposition to find ways to adjust the accord so that it enjoys broader support.
