ADDIS ABABA, Ethiopia - Violence flared again Monday in Ethiopia's restive Oromia region, where dozens of people were killed a day earlier in a stampede when police tried to disrupt an anti-government protest amid a massive religious festival.
The state broadcaster late Monday raised the death toll to 55 from the earlier official count of 52. Its report cited a hospital official in the town where the stampede occurred, and it said three people remained hospitalized with serious injuries.
After the stampede, clashes between security forces and protesters erupted Sunday evening and continued Monday morning in the towns of Bishoftu and Ambo, an Ethiopian government official and witnesses told The Associated Press.
Relatives of those killed in Sunday's stampede were flocking to Bishoftu, 45 kilometres (27 miles) southeast of the capital, Addis Ababa, raising tensions, said Nimona Negash, a driver of a small motorized taxi called a tuk-tuk.
The annual Irrecha thanksgiving festival had drawn huge crowds, and the stampede occurred as people ran to escape police firing tear gas and rubber bullets and shooting live rounds into the air after anti-government protesters approached the stage where religious leaders were speaking.
People were crushed to death. A witness said some of those killed were still being recovered from ditches where they fell while trying to flee.
There also were reports of arrests.
"Some people tried to come out en masse this morning to protest the deaths of holiday-goers on Sunday and also demand the release of people arrested during the celebrations," Negash said. "Today's protesters were peaceful but dispersed by police violently. I'm not aware of any deaths this morning, but it was violent. But I'm aware of live bullets used this morning in other vicinities of this town."
He said he saw seven bodies pulled from a deep ditch until he could no longer stand to watch.
The Oromia region has been experiencing deadly anti-government protests since November 2015 as people call for wider political freedom and the release of detained opposition figures and journalists.
Ethiopia's government, a close security ally of the West, has been accused of quashing dissent and blocking internet access. The U.S. recently spoke out against what it called the excessive use of force against protesters, calling the country's situation "extremely serious."
On Monday, Human Rights Watch called for an independent investigation and said the government should "end the use of deadly force to quell largely peaceful protests that began nearly a year ago."
Ethiopia's government is accusing the protesters. President Mulatu Teshome Wirtu, on a state visit to Italy on Monday, blamed the stampede on "the action of some hooligans," the Italian news agency ANSA reported.
The head of the Oromia region's spokesman's office, Fikadu Tessema, told the AP on Monday that some groups were trying to "continue the violence that they orchestrated on Sunday."
He said they were trying to portray the stampede as caused by live bullets fired by government forces.
"I can assure you 100 per cent that all the 52 victims died of a stampede and didn't have bullet wounds on their bodies," he said. "The current situation in Oromia is not out of control. We are taking measures to bring back our peace."
