Ousted leader Aung San Suu Kyi asked the people of Myanmar to stay "united" in the face of military rule, her lawyers said yesterday, as she reappeared in a junta court. 

The Nobel laureate, and daughter of independence hero General Aung San, has been under house arrest since a February coup that sparked huge pro-democracy protests the junta has tried to crush with deadly force.

Invisible to the outside world bar a handful of courtroom appearances, Suu Kyi, 76, has been hit with an eclectic raft of charges. She could face more than a decade in prison if convicted on all counts.

She is accused of a series of offences ranging from bribery and violating coronavirus protocols to illegally possessing two-way radios and incitement to commit crimes against the state - allegations her lawyers reject.

Yesterday, she heard testimony that she flouted coronavirus restrictions during elections her National League for Democracy (NLD) party won by a landslide last year, her lawyer Min Min Soe told reporters. 

Min Min Soe also told reporters that Suu Kyi had urged people to "Please stay united. Please be united".

The specially-convened court in the capital Naypyidaw also heard testimony on a separate charge of sedition, although Suu Kyi's legal team argued two documents submitted by the prosecution were inadmissible as they were unsigned.

Her legal team head Khin Maung Zaw told Reuters the prosecution had entered evidence he believed was inadmissible, but the judge allowed it.

The evidence includes letters the prosecution says were issued by Suu Kyi's NLD party in the days after the coup which were widely shared on social media.

One urged embassies not to recognise the junta, among several documents that Khin Maung Zaw said were signed by neither Suu Kyi nor her co-defendants, ousted President Win Myint and former Naypyitaw mayor Myo Aung.

Myanmar has been in turmoil since Suu Kyi's ouster, with huge protests, renewed clashes between the military and ethnic rebel armies in border regions and an economy spiralling into freefall.

Junta leader Min Aung Hlaing has justified his power grab by citing alleged electoral fraud in the November poll won by the NLD.

In an interview with Russian news agency Sputnik published on Monday, Hlaing said Suu Kyi's fate was not in his hands.

The military has cracked down brutally on dissent -- shooting protesters, arresting suspected dissidents in night raids, shutting down news outlets and rounding up journalists.

More than 880 civilians have been killed, according to a local monitoring group.
