Yangon: A Myanmar woman has been detained by the military junta over a Facebook post celebrating the 80th birthday of jailed democracy leader Aung San Suu Kyi, according to local media reports.

Suu Kyi, once the figurehead of Myanmar’s democratic transition, has been held in custody since the military seized power in a coup in February 2021. She is currently serving a 27-year sentence on charges widely condemned by rights groups as politically motivated and fabricated.

Her birthday on Thursday passed behind bars, with her son calling on supporters to share public messages of solidarity.

Over the weekend, Myanmar’s military government said it had arrested two Facebook users for "inciting and spreading propaganda on social media with the intention to destroy state stability."

One of those arrested -- Hinn Yin Phyu -- was reportedly detained on Saturday at a staff residence for employees of state-run broadcaster MRTV in the capital Naypyidaw. The junta’s statement did not specify the content of her alleged post.

However, independent media outlet Democratic Voice of Burma (DVB) reported that Hinn Yin Phyu is an MRTV employee and was arrested after posting a birthday message to Suu Kyi. The now-deleted post read:

"May you live long and be free from illness, may you be free from the suffering caused by separation from your loved ones throughout your life, and may you only meet good people."

Facebook remains the most widely used social media platform in Myanmar, despite ongoing digital restrictions and surveillance following the military takeover.

The junta regularly issues vague public notices regarding arrests tied to online activity, though these often omit key details about the supposed offences. A spokesperson for the military government could not be reached for comment.

Aung San Suu Kyi, a Nobel Peace Prize laureate, first rose to international prominence for her non-violent opposition to military rule and her refusal to leave the country during her earlier house arrest. While she led Myanmar during a period of partial democratic reform, her global reputation suffered after she defended the military's actions during a brutal crackdown on the Rohingya Muslim minority.

The 2021 coup ended Myanmar's brief democratic interlude, igniting mass protests that were violently suppressed. Since then, the country has spiralled into civil conflict, with pro-democracy groups and longstanding ethnic armed factions now waging guerrilla warfare against the junta.
