The son of Myanmar's detained former leader Aung San Suu Kyi said a visit by a delegate of the International Committee of the Red Cross was the first positive development concerning her in more than five years."This may be a first step, but it must not be the last," Kim Aris said in a statement, adding he has not yet received independent confirmation of his mother's condition or wellbeing.The meeting was the first publicised visit between her and a foreign official since she was ousted in a 2021 coup. The military deposed Suu Kyi in February 2021, jailing the Nobel Peace Prize laureate and triggering an ongoing civil war that has killed more than 100,000 people, according to monitor ACLED.The coup leader and former junta chief, Min Aung Hlaing, was installed as civilian president in April following highly restricted elections.The images could not be verified by AFP but artificial intelligence tools found no instances of fabrication.

"We can know now that she's alive."However, Aunty should be released immediately as she's being detained unlawfully."Suu Kyi being used as 'bargaining chip'Authorities have not disclosed the exact location of Suu Kyi's detention in the capital Naypyidaw, nor how many years of her sentence remain.Her son, Kim Aris, a British national, has sought independently verified proof that his mother is alive after she was transferred to house arrest.Aung San Suu Kyi's son, Kim Aris, has fought for the release of his mother for years.
