Myanmar military authorities have moved former leader Aung San Suu Kyi from her house arrest to solitary confinement in a prison complex in Naypyidaw, the military-built capital.

"According to the criminal laws (...) I have been placed in solitary confinement in a prison" in the capital, a spokesman for the military regime, O Min Tun, said in a statement.

Since her overthrow in the February 2021 coup, Sochi has been under house arrest in an unknown location in Naypyidaw, according to sources, and has only left it to attend her court hearings in the military court, which could sentence her to more than 150 years in prison.

Her lawyers are also prevented from speaking to the media and journalists cannot attend her trial.

Sochi was arrested hours before the February 1, 2021 coup. Critics of the ruling military council say the accusations against her were trumped up to ensure that she does not return to political life.

The former leader faces several charges, including violating a colonial-era state secrets law, electoral corruption, disobedience and corruption.

And last December, a special court sentenced Sochi to four years in prison, the first of several cases it has tried since the army ousted it.

It is noteworthy that Sochi was awarded the Nobel Peace Prize for her struggle against the military's domination of power over the past decades, but she faced harsh criticism after she supported the genocide campaigns against the Muslim Rohingya minority in recent years, and many called for her to be stripped of this international award.
