Armed forces opposed to Myanmar's militaries seized a police station in the eastern town of Mobye on Sunday, according to local media reports.
At least 13 members of the security forces were killed and 4 were captured.
Irrawaddy, a Myanmar media outlet, quoted a fighter from the local People's Defence Force as saying the police station had been set on fire and two civilians had been wounded.
Other media reports claim that up to 15 members of the security forces had been killed.
On 1 February, Myanmar’s military overthrew the government and declared a year-long state of emergency. The military has placed under house State Counselor Aung San Suu Kyi and President Win Myint, along with other top officials it has accused of election fraud.
