There is a renewed effort to restore peace in Nicaragua. But is it coming too late? Angry demonstrators have flooded the streets in recent days, challenging the rule of President Daniel Ortega. More than two dozen are dead, and hundreds injured or imprisoned. Our correspondent Sean Callebs explains what's at stake.

Widespread looting. Coupled with protests from Nicaraguans furious that the country's president Daniel Ortega planned to overhaul social security system. For many, it was the final straw.

ENRIQUE BONILLA, DEMONSTRATOR "Nicaragua was a pressure cooker - it was just a matter of time for the ten years of repression, for the ten years of electoral fraud, for the ten years of when we could not take to the streets to protest freely - they are over."

On Sunday, Ortega cancelled the planned changes to the social security system -- And, while he is blaming right wing insurgents for the violence - there is no question the fuse is lit.

DANIEL ORTEGA, NICARAGUAN PRESIDENT "The incidents of violence that have happened are regrettable - we express solidarity with all the families whose loved ones have died from the violence."

Human rights groups say at least 25 are dead --- including students, journalists, and a police officer. The country's Episcopal Conference is agreeing to step in - listen, and work with all sides to find a peaceful way forward, but with one stipulation.

LEOPOLDO BRENES, NICARAGUAN CARDINAL "To ease the climate for dialogue, we believe it's essential and mandatory that the government as well as each member of civil society avoids any acts of violence."

That demand is important for two reasons. One, Ortega HAD said, he would not take part in any negotiations with pre-conditions. But he is agreeing the church's plea. Secondly - dozens of students arrested during the protests are starting to be freed. They have their heads shaved --- and allege torture at the hands of authorities.

SEAN CALLEBS, WASHINGTON "Since the outbreak of violence more than a week ago, Ortega's government has urged the collection of workers, employers, and pensioners back to the negotiating table. But observers say the demonstrations have taken on a life of their own and spread beyond the frustration of social security cuts. And, now many are wondering if Ortega -who has been in power since 2007 - can withstand the intense pushback. Sean Callebs, CGTN, Washington."
