Colombia president says "demented" FARC attacks could end peace talks

BOGOTA (Reuters) - Colombia's President Juan Manuel Santos warned on Tuesday that continuing attacks perpetrated by leftist FARC guerrillas, many of which target infrastructure, could bring an end to peace negotiations with the government.

The threat was made weeks after Santos' successful re-election campaign, which made much of agreements he had reached with the rebels on more than half the agenda for peace talks that he initiated in late 2012 to end a half-century of war.
