Rakhine has been gripped by violence since October last year when a bloody military crackdown was launched that the UN believes may amount to ethnic cleansing of the Muslim minority Rohingya, AFP wrote.
More than 70,000 Rohingya villagers fled across the border to Bangladesh, carrying with them stories of systematic rape, murder and arson at the hands of soldiers. The major part of the military campaign ended several months ago, but fear continues to stalk the region amid sporadic bouts of violence.
Officers said Saturday that the government had deployed a fresh batch of troops after a recent spate of murders. They said soldiers have been sent to a mountainous area where a band of militants is actively training.
"Many battalions with hundreds of soldiers from central Myanmar were deployed to the Mayu mountain range," a military officer said.
State media also reported that the government had imposed new curfews, to be set "in necessary areas" as the army beefs up its "clearance operations".
A Rohingya villager told AFP his community feared a repeat of last year's crackdown.
"Some Muslim villages in Rathidaung dare not to go outside," said Hasumyar, who only gave his first name and lives in a township that has been placed under curfew.
Reports of an army battalion being flown into Rakhine to boost security were met with criticism on Friday by UN special rapporteur Yanghee Lee, who warned the development was "a cause for major concern".
The UN has accused the military of committing grave abuses against the Rohingya during its military crackdown.
But Myanmar has dismissed the allegations and vowed to block a UN probe into the violence.
Buddhist-majority Myanmar has long faced criticism for its treatment of the more than one million Rohingya, who are denied citizenship and struggle to access basic services.
The minority group is widely reviled as illegal migrants from Bangladesh, despite having lived in the area for generations.
