Colombia’s bid to end more than five decades of armed conflict with the Revolutionary Armed Forces of Colombia, known as FARC, has failed, with Colombians voting against a peace deal, according to an Oct. 2 report by The Washington Post.

Following six years of negotiations, the deal was put to a vote, and the expectation was for a 2-to-1 vote in favor of ending the conflict.

However, the deal failed to pass after 50.25% of votes were cast against the agreement that would have seen rebels hand over their weapons to U.N. observers in the next six months.

Many Colombians, including former President Alvaro Uribe, reportedly called for an agreement that punished the FARC's top leaders.

President Juan Manuel Santos has been pushing for a peace deal since 2011, and his supporters now want FARC leaders and the government to reopen the agreement. However, Santos is not in favor of the move.
