(CNN) -- A nervous calm settled over northwest Peru on Monday night, three days after clashes between indigenous citizens and national police left more than 30 dead and 50 wounded. Alberto Pizango, a leader of the protesters, says his followers did not kill police officers. A 3 p.m.-6 a.m. curfew seemed to be holding, and both sides in the bloody episode said they wanted dialogue, not bullets. "The situation is much more tranquil," foreign minister Jose Andres Garcia Belaunde told CNN. "There's the possibility of entering into a dialogue." The violence started Friday when national police attacked a roadblock near the city of Bagua in the Amazonian part of northwestern Peru. About 2,500 indigenous people had blocked the main road to protest measures the government has taken to sell land to energy companies and other businesses. Indians native to the area say that it is their land even though they don't have formal property titles.
