In Washington, State Department spokeswoman Victoria Nuland said the U.S. was deeply concerned about the reports and urged restraint.
Casualties from several townships were taken were taken to a hospital in Sittwe, the state capital not yet hit by the latest round of violence. There, Aung Moe Khaing, 25, told The Associated Press he was shot Tuesday when soldiers dispersed the crowd. He was wounded in an arm and a leg.
Phyu Thein Maung, 39, from Yathetaung township, said he was shot in the buttocks.
"Muslims provoked us from inside their village and challenged us from their community, guarded by soldiers," he said. "People were very angry as they shot iron spikes at us with catapults and made abusive gestures. I was hit by a gunshot when soldiers dispersed the crowd."
There have been concerns in the past that soldiers were failing to protect the Rohingya community, but accounts this time from Rakhine villagers suggest that Myanmar's military may have been defending the Rohingya.
The crisis has proven a major challenge to Thein Sein's government and to opposition leader and Nobel Peace laureate Aung San Suu Kyi, who has been criticized by some outsiders as failing to speak out strongly against what they see as repression of the Rohingya.
The U.N. warned Thursday that the crisis had sent a new wave of refugees to seek shelter in camps already overcrowded with 75,000 people from the June violence.
Bangladesh has put its border guards on alert, fearing a new influx of Rohingya refugees.
On Thursday, Bangladesh border guards turned away 45 Rohingya trying to enter into Bangladesh by boats, said Lt. Col. Khalequzzaman, a border commander.
Local police chief Selim Mohammad Jahangir said Friday that at least another 3,000 Rohingya Muslims had been spotted on about 40 boats on the Naaf River off Bangladesh's Tekhnaf coast.
Bangladesh says it's too poor to accept more refugees and feed them. Bangladesh is hosting about 30,000 Rohingya who fled Myanmar to escape government atrocities in 1991.
