Venezuela's government and opposition have agreed to an anti-violence pact to lower tensions over the rule of President Hugo Chavez.
The agreement includes references to freedom of expression, the media's role in promoting peace, condemns violence and also urges a toning down of aggressive language, the source said.
The eight-point resolution was the first firm development from three months of talks guided by the Organization of American States (OAS) and backed more recently by a six-nation group led by the United States.
But a source close to the talks said the document carried no sanctions and the feuding sides appeared no closer to a deal on elections to end their political conflict in the world's fifth-largest oil exporter.
OAS Secretary General Cesar Gaviria said the government and opposition would sign the resolution today.
At least seven people have died in clashes or violence during rallies and marches since December when the opposition started a two-month strike that failed to oust a president who they accuse of ruling Venezuela like a dictator.
Mr Chavez, a retired paratrooper whose populist speeches often carry aggressive class warfare references, accuses his enemies and private media stations of being "terrorists" conspiring to topple him.
But his opponents say the president has inspired his mostly poor followers to acts of violence with his tirades against the "rich elites" he says have long robbed the nation of its huge oil wealth.
Mr Chavez has recently toughened his stance since opposition leaders called off their strike that tried to push him from office by starving the state of its vital oil revenues.
