Myanmar's ousted leader, Aung San Suu Kyi, has been remanded in custody until Wednesday, not Monday as previously thought, her lawyer told media, as protesters began gathering again to demand her release and an end to military rule.

Security forces in Myanmar deployed armored vehicles in major cities two weeks after the military overthrew Suu Kyi's government and detained her on charges of illegally importing six walkie-talkie radios.

Her detention was due to expire Monday but her lawyer, Khin Maung Zaw, told media a judge at a court in the capital, Naypyitaw, had said she was remanded until Wednesday.
