BOGOTA, Colombia (AP) — Small farmers have launched a nationwide strike in Colombia less than a month before the presidential election. They accuse the government of failing to adhere to agreements reached after a violent work stoppage last year.

Cesar Pachon is the spokesman for farmers in the central department of Boyaca. He said Monday that the strike will continue indefinitely until the government of President Juan Manuel Santos helps resolve problems that include the farmers' debts of more than $1 billion.

Pachon estimates that 100,000 farmers have joined the strike so far.

No violent incidents have been reported.
