CARACAS, Venezuela  Peru’s Congress on Thursday overturned two decrees by President Alan García that were aimed at opening large areas of the Peruvian Amazon to logging, dams and oil drilling but set off protests by indigenous groups this month in which dozens died.

The move appeared to ease tensions with the indigenous groups, which had continued with their protests and road blockades in parts of Peru despite Congress’s decision to suspend the decrees last month. After the vote on Thursday, however, some indigenous leaders said they would lift the scattered blockades and halt the protests.

“Today is a historic day for all indigenous people and for the nation of Peru,” said Daysi Zapata, a leader of the Peruvian Jungle Inter-Ethnic Development Association, a group representing more than 300,000 people from Peru’s indigenous groups.

The apparent end to the impasse came after at least 24 police officers and 10 civilians were killed in clashes and acts of retaliation in northern Bagua Province, some of Peru’s bloodiest political violence since a two-decade war ended in 2000.
